The best reusable water bottles (as a gift or for yourself)

It’s the 21st century and single use plastic bottles will just not do. We are producing over 300 million tons of plastic every year, half of which is single-use plastic, not to mention that constantly buying new bottles can make a significant dent in your budget. Plastic bottles aren’t just bad for the environment and your pocket, but they’re also bad for your health (unless you like ingesting small pieces of microplastic).

This all boils down to one thing: reusable bottles can be very useful. Thankfully, there’s no shortage of them on the market — if anything, there’s almost too many to choose from. You can find reusable bottles from multiple materials and with various functionalities: from the ultra-fancy self-cleaning ones to the basic, sleek, and cheaper bottles.

So I thought I’d make your job easier and scoured the internet, analyzing different bottles and seeing which ones work best. Here are some of my favorites.

1. The smartest water bottle: Smartech LARQ ($90)

This is almost without a doubt one of the best reusable bottles you can find on the market — and it has the price to show it.

We all know how annoying it is to take care of your bottle, and probably most of us forget to wash it every once in a while so it gets a bit dirty and, in time, the water starts tasting a bit fishy. Well, you don’t have to worry about that at all with the new LARQ bottle. This ingenious bottle has a self-cleaning system that intelligently turns on every 2 hours to keep your water and bottle fresh. Besides cleaning your bottle it also purifies your water, using UV-C LED light in order to eliminate 99.99% of bio-contaminants. You can even use it for outdoorsy adventures if you want to drink from a spring. I mean, how cool is that?

The bottle comes in two sizes and several colors and there are a few models out there. It’s also pretty sturdy and looks sleek, you shouldn’t have any problems fitting it into your bag or backpack. If you’re willing to pay a premium to have an innovative long-lasting and self-cleaning bottle, the LARQ is the way to go.

2. The best collapsible water bottle: Stojo water bottle ($25)

When convenience is the name of the game and space and weight are your main concerns, this might be the water bottle to go for.

It has a very modern and elegant style, but the best thing about it is that is really lightweight and collapsible, so after finishing your drink, it won’t take up much space from your luggage, it’s small enough to fit in your pocket.

When full, the bottle is very well balanced and it feels sturdy so you won’t have to worry if you keep it on your desk. With the lid attached to the bottle you also won’t have to worry about losing the cap ever again and the silicone material is not only BPA free but it also doesn’t taint the water’s flavour. Come to think of it, even without being collapsible it’s just a good all around bottle.

3. The best stylish thermos bottle: Teabloom bottle ($25)

If you are the kind of person that wants something stylish, a bit more eco-friendly, with maybe more functionality so you don’t have to buy more than one bottle, it seems like Teabloom is right for you. This water bottle is BPA-free, and made of stainless steel and 100% organic bamboo which makes it incredibly stylish. It keeps your water cold for 24 hours and hot for 12.

The functional accessories allow you to infuse the water with fruits, brew tea, and even cold-brew coffee. You can take this bottle with you to your yoga practice, at the office, or even for outdoor activities. It’s the perfect mix of practical and stylish — it doesn’t get much better than this.

4. The best everyday use filter bottle: Brita Fill & Go ($21)

I’ve been using my Brita Fill & Go bottle for a couple of years now and I simply cannot imagine my day to day life without it. It’s made of BPA-free hard but light-weight plastic is super durable which makes it suitable for traveling or taking it to the office/gym. I’ve dropped mine several times and it’s still intact but the cap suffered some damage throughout time and unfortunately, you can’t find replacements for that, which is probably the only downside I could find. The filtering is done while you drink the water through the nozzle, and you have to replace your filter every 4weeks or so, but even so, it’s still so much cheaper than buying bottled water.

This is almost certainly the best value for money you can get. It’s a no-fuss reusable bottle that just gets the job done. Use the Brita Fill & Go water only with fresh potable tap water, it is not safe to use in areas where the water is not safe to drink as the bottle’s carbon filter won’t filter out bacteria, viruses and other microorganisms.

5. The best outdoors filter bottle: Grayl Geopress Purifier ($69)

If you like hiking and traveling, this is probably the bottle for you. The bottle holds 720ml (24 oz) of water, and is not only incredibly durable but it also filters out 99.99% of bacteria, viruses, and even heavy metals. It has a very good grip, so it won’t slip while venturing outdoors and with the SimpleVent cap your water stays protected from cross-contamination.

It feels very nice in the hand and the pressure surface makes it easy to drink from on the run or while cycling. It’s sturdy and excellently suited for any form of outdoor activity. If you have an active lifestyle, this is probably the bottle for you.

6. Best glass water bottle: Ello Syndicate with one-touch flip lid ($17)

Probably one of the most versatile water bottles out there due to its looks, this glass water bottle comes with a silicone sleeve that protects the bottle from any chips and cracks, a very important aspect to keep in mind when it comes to glass bottles. The touch flip lid is super convenient and lets you drink directly from the glass without touching any plastic or silicone. Even though it is a bit heavier than a normal plastic bottle, some customers declared that the water tastes better with no plastic/metal aftertaste whatsoever. Don’t let the glass bottle fool you: the silicone casing makes it far sturdier than you’d expect.

This is also one of the better value bottles out there, as you’ll get it cheaper than most on this list, while making no compromise on quality.

7. Best stainless steel water bottle/flask: Vacuum Insulated Hydro Flask ($44)

This easy-to-carry flask will help keep your water cold and thanks to its wide mouth you can also add some extra ice cubes for those super hot summery picnics or outdoor activities. It keeps water icy cold for 24 hours, and it can also hold hot drinks for up to 12 hours, in case you need a cup of tea or coffee on the go (especially considering this period’s weather).

What I find very convenient about this bottle is that it has interchangeable caps, and you can choose between a wide mouthed cap or a straw cap, which makes it even more versatile for a variety of activities.

8. Best infuser bottle: Pressa Bottle ($38)

If you find plain water simply boring (I feel you), the Pressa Bottle upgrades your tap water to a super fruity and healthy version with its built-in juice press. How amazing is that?

This dishwasher-friendly bottle comes with a silicone sleeve, which will protect the bottle from any breakage and it’s also BPA-free as it is made of glass. The bottle is a bit heavier compared to other reusable bottles, but this makes it also sturdier and more durable. The only problem that you’ll have with this bottle is thinking of the perfect combination of fruits and aromatic plants to enjoy the most with your water.

9. Best water bottle for kids (plastic): Eddy Kids by CamelBak

When looking for kid’s water bottles, you need something that is both resistant and lightweight and also looks fun. The Eddy Kids water bottle by CamelBak has both of these plus a very cute design that’s bound to make the little one love the bottle.

It comes with their signature Big Bite Valve, which helps to eliminate spills when drinking by allowing the kids to bite down the straw to get the water out. The integrated loop is a very nice feature that makes the bottle easy to carry for children’s small hands. It comes in a variety of designs for any taste and I am glad to say that most of the designs and colors are gender-neutral.

10. Best water bottle for kids (non-plastic):Hydro Flask Kids ($37)

If you worry a lot about the micro-plastic particles that are ingested by your children every day (and you should, given that studies have shown we all eat and drink a lot of microplastic) you might want to know what options you have in terms of non-plastic alternatives for your child.

To my eye, the Hydro Flask is not only excellent for adults, but their small children variety is also great quality. As is the case with the normal-sized version, the kid’s flask is made of stainless steel and it has interchangeable caps including one with a straw. The color variety is also nice to suit everyone’s needs.

11. Best (cheap) sports water bottle: Gatorade water bottle ($11)

I believe a good water bottle is a good investment. I really do. But let’s face it — some of these are expensive and sometimes, you just want something cheap that works.

When it comes to sports water bottles, well the variety is huge, and the prices vary greatly as well. This bottle’s design doesn’t say much but it has a very interesting characteristic: you can only drink water from this bottle when you squeeze it and it won’t leak in your bag otherwise. Pretty basic, but really useful if you don’t want to get all your gym gear soaked. It appears that this bottle is not only really good for holding water, you can also add some electrolytes to the water with no problem, and even add some protein powder. The Gatorade water bottle is both versatile and cost-friendly.

12. Best water bottle for your handbag: Memobottle ($36)

Let’s face it, a normal water bottle can be annoying if you want to carry it with you in a normal handbag, or a small backpack. This is where the Memobottle, the flat water bottle, truly shines. It’s made of BPA-free plastic, and it comes in a variety of notebook sizes (A4, A5, etc) to suit your needs. You can simply put it in your bag along with your notebooks and even laptop, without making your bag bulkier or taking up too much space. How ingenious is that?

It looks fancy and stylish and it’s one of those small design things that can really make an important difference, especially if you’re looking for something a little more different.

United Nations hosts key climate emergency summit in New York

More than 60 world leaders will convene today for a UN summit on “climate emergency” aimed at reinvigorating the Paris agreement on climate change, at a time when mankind is releasing more greenhouse gases into the atmosphere than at any time in history.

Countries are expected to announce new actions to limit the causes of warming or to speak on initiatives developed by a coalition of nations. UN secretary-general António Guterres had asked countries to commit to net-zero emissions by 2050, reduce subsidies for fossil fuels, and stop building new coal-fired power stations.

“People want solutions, commitments, and action. I expect there will be an announcement and unveiling of a number of meaningful plans on dramatically reducing emissions during the next decade, and on reaching carbon neutrality by 2050,” said Guterres.

Who is attending?

Among the list of those absent will be US President Donald Trump, who pulled his country out of the Paris Agreement upon taking power. Brasilian president Jair Bolsonaro, under whose leadership the Amazon rainforest is continuing to burn at record rates, will also be absent.

On the other hand, China, the world’s biggest carbon emitter by far, but also a leader in the renewables sector, will be present and represented by foreign minister Wang Yi, with Guterres hinting last week that the East Asian giant will be committing to new measures.

“There’s a tension between the countries that want to go ahead to translate their goals into real policies and those that do not,” said Laurence Tubiana, CEO of the European Climate Foundation and one of the architects of the Paris agreement. “We can hope for the best.”

India’s Prime Minister Narendra Modi will speak in the morning session, along with the leaders of New Zealand, the Marshall Islands, and Germany’s Angela Merkel. Like China, India is coal-addicted but has also set itself highly ambitious renewable energy targets, particularly in the solar energy sector.

What are the expectations?

Seventy-five countries are expected to bring enhanced commitments. But officials have also been careful to manage expectations and said today’s summit is also a run-up event to the 2020 UN climate summit that the UK will host in Glasgow. Still, there is some sense of increased urgency.

The goal of “carbon neutrality” — where most emissions are eliminated and those that remain are offset (by measures such as the planting of new trees and, potentially, carbon capture technology in the future) was considered so radical in 2015 that it was left out of the text of the Paris agreement.

Now, though, it has become a rallying cry for countries like the United Kingdom and France as well as major corporations, who are leading the charge in countries like the US where the political leadership has sought to distance themselves or even undermine the cause.

Six essential science books that read like hot cakes

I know, I know that’s not a real saying — but for too many people, science books just sound rough and unfriendly. Here, we’ve selected science books that read like fiction, so you can thoroughly enjoy yourself while reading. We’ve also handpicked the books we see as essential, the very best of the best. This is only a starter pack — stay tuned for more.

Silent Spring by Rachel Carson

Buy on Amazon

What started as a series of articles in the New Yorker from 1958-1962 essentially kickstarted the environmentalist movement. Rachel Carson documented the effects of pesticide on the environment, looking in particular on the dramatic effects that pesticides have on songbird. She prophesized that one day, if we continue in the same fashion, we’d have extinguished all of nature’s songbirds, and the world will go silent.

Carson also accused the chemical industry of spreading disinformation and public officials of accepting industry claims unquestioningly. The book was met with fierce opposition and lobby by the chemical industry, but it ultimately spurred a reversal in national pesticide policy, leading to a nationwide ban on DDT for agricultural use. Her bleak warning is now more important than ever. Although more than 50 years have passed since Silent Spring was written, we are still facing similar concerns. This is the book that started it all.

Universal, A guide to the Cosmos by Brian Cox and Jeff Forshaw

Buy on Amazon

Although this is a newcomer, being published in 2017, it’s set to become a classic. Why? It’s simple, really — it does what it says on the cover. It’s a guide to the cosmos, in a way that’s fun and engaging, with bonus points for the simplest and neatest explanation of general relativity I’ve ever read.

Brian Cox is already one of the most respected science communicators and Jeff Forshaw is a particle physicist at the University of Manchester, also working on the LHC. Together, the duo created a format that doesn’t require any previous knowledge, managing to put together a book that’s suitable for all readers. All you need is curiosity. You can read our full book review here.

The Voyage of the Beagle by Charles Darwin

Buy on Amazon

I know what you’re thinking — you’re surprised this isn’t The Origin of Speciesand you’re absolutely right. The Origin of Species is Darwin’s masterpiece and possibly the most influential and important science book in history — but it’s not an easy read. It’s a good read, don’t get me wrong, but I’ve always felt that if you want to read The Origin of Species, you just do it without any need for a recommendation. But for laypeople, it might not be that accessible, and for those who are really into biology, you might find a lot of outdated information. Meanwhile, The Voyage of the Beagle reads more like an adventure book and features Darwin’s own thoughts and remarks. You get to see his mind gnawing at the idea of evolution, observing the patterns between different species in different ecosystems.

Darwin’s insatiable thirst for knowledge and exploration shines in this landmark book — and if you like it, it’s also the perfect gateway drug to Darwin’s other works.

What is Life? by Erwin Schrödinger

Buy on Amazon

Have you ever wondered how a Nobel-winning physicist sees the world? A classic among both biologists and physicists, What is Life does just that — it explores how living organisms differ from inanimate objects like crystals.

The book is based on a set of Schrödinger’s public lectures delivered in 1943. The lectures attracted an audience of about 400 people, who were warned that “the subject-matter was a difficult one and that the lectures could not be termed popular, even though the physicist’s most dreaded weapon, mathematical deduction, would hardly be utilized.” Both James D. Watson, and Francis Crick, who jointly proposed the double helix structure of DNA based on X-ray diffraction experiments by Rosalind Franklin, credited Schrödinger’s book with presenting an early theoretical description of how the storage of genetic information would work.

The Making of the Atomic Bomb by Richard Rhodes

Buy on Amazon

The definitive history of nuclear weapons and the Manhattan Project, The Making of the Atomic Bomb documents one of the most defining moments in human history: the creation of the atomic bomb. Richard Rhodes, an American journalist and historian, writes about science, the people, and the socio-political realities that led to the development of the atomic bomb.

What really gets the story going is that many of the characters speak for themselves — in long paragraphs of direct quotation. The book is also riveted with detailed, lesser-known facts about the affairs, and delicious irony. The scope and implications of the story in the book are just as enticing as the story itself.

Great Dialogues by Plato

Buy on Amazon

We’re ending with a blast from the past, and a book that isn’t, strictly speaking, science. But Plato’s Dialogues are the most influential body of philosophy of the Western world — and will continue to remain so for the foreseeable future. It’s not just that Plato deals with incredibly complex topics ranging from what is beauty, to what is the best political system, but it’s the way he does it. You can see his brilliant mind at work, and the same can be said for Socrates — who is the main character in many of Plato’s dialogues.

Written in the form of debates, the Dialogues are based discussion of moral and philosophical problems between two or more characters, a discussion that often involves Socrates, who was Plato’s mentor. In Greek, philosophy translates as “love of wisdom” — and this is brilliantly evident from the book. Caution: this may serve as a gateway drug, and may lead to obsessive reading of philosophy and debate.

Never tie your shoes again with lock laces

If I’m leaving in a hurry, the thing I hate the most is tying my shoelaces. The black magic through which shoelaces untie themselves is equally annoying — and this is where these laces come in. Simply put them on the shoelace, tuck them in once and that’s all there is to it. You show those strings who’s boss! (tamer colors such as black or brown also available)

The soul of an octopus (Disclaimer: not an actual soul of an octopus)

No list would be complete without a book, and this is one that really stands out. Sy Montgomery is a renowned naturalist. Here, she details a moving encounter with an octopus, and how it prompts a meditation on consciousness, the soul, and an animal that gets a lot of unneeded negative publicity. Definitely a book worth reading, guaranteed to change your perspective on the ever-surprising octopus.

9 Valentine Gift Ideas to Bring Out the Geek in You

Valentine’s is all about recognizing the uniqueness of your significant other — after all, there’s only one of them, and that’s what drew you two together in the first place! We’ve scoured the Internet for ideas on how best to mix the celebration with our love of knowledge in all its aspects and, so far, we’ve arranged these ideas in different academic themes.

Some of the objects we’ve run into, however, didn’t make the lists as they don’t fall squarely into a single field. Just like our better halves, they are unique, we like them very much, and the celebration just wouldn’t be the same without them. So here are the coolest, geekiest Valentine gift ideas that were just too themselves to fit in our well-ordered lists.


That old-timey recruitment poster is still strong in these posters, and they’re bound to light a little spark of adventure whenever your boo sees them — an adventure they’ll love to take you along for. Extra V-points if you pair the “Empire needs you” poster with a Darth Vader mask. One that you’re wearing, of course.

Put the Moon in the palm of their hand

Love makes you do silly things — things like promising your paramour you’ll bring the moon down in the palm of their hand. Obviously, since it’s so far out there (pun intended) that nobody actually expects it to happen. It’s just a nice, sweet nothing to be shared among lovers.

But just how awesome of a Valentine will you be when you actually do it? Cosmically awesome! Take the Moon lamp put the moon in your date’s hand.

And the stars at their fingertips

The second part of the “moon and stars”, this chart will both look awesome and educate. Can’t beat that combo. It’s quite big, so it would probably work best if you can set it up beforehand. So if you’re living with your Valentine (lucky you) or if you can otherwise prepare the chart before the big night, present them with the moon first and sweep them off their feet with the stars when they least expect it — once everyone’s back home.

Oh, also, it’s handmade.

Unique Science Jewelry Gifts for Valentine’s Day

If you’re flat out of ideas for this year’s Valentine Day, you can never really go wrong with jewellery. Here are just a few of the most interesting accessories I found.

Spell out your love and happiness with chemistry

What is love? It’s an age-old question with likely no satisfying answer. What seems certain is that nature has developed an irresistible cocktail of chemicals to help us fall in love (and hopefully pass on our genes).

Serotonin necklace

It’s one of love’s most important chemicals that may explain why when you’re falling in love, your new lover keeps popping into your thoughts. In one study, researchers discovered that serotonin levels of new lovers were equivalent to the low serotonin levels of Obsessive-Compulsive Disorder patients.

Dopamine necklace

Lovestruck couples have high levels of the neurotransmitter dopamine. This chemical stimulates ‘desire and reward’ by triggering an intense rush of pleasure.

Adrenaline necklace


The initial stages of falling for someone activates your stress response, increasing your blood levels of adrenalin and cortisol. This has the charming effect of making you sweat, making your heart race and your mouth go dry when you unexpectedly bump into your new love.

Oxytocin necklace

Oxytocin is a powerful hormone released by men and women during orgasm. The chemical helps deepen feelings of attachment, cementing relationships and making couples feel much closer to one another.

Solar system bracelet

A great unisex accessory for that special someone who always has eyes for the stars. Features all the planets, the sun, the moon, and a black hole.

DNA ring

A lovely double-helix ring that makes for a nice gift for any occasion.

Or maybe some DNA earrings

A cute X-rayed cat pendant

A beautiful pendant showing the detailed skeleton of a feral cat finished with black epoxy. Perfect for people who love cats and radiology.

Or, if she likes ravens more, this:

Nerve cell bracelet

Make a statement with this brainy bracelet shaped like a neuron.

Anatomical heart charm

If you’re going for the anatomically correct representation of “I heart you.”

Octopus tentacle pendant

The octopus is the only animal that has a portion of its brain (three quarters, to be exact) located in its (eight) arms. Without a central nervous system, every arm “thinks” as well as “senses” the surrounding world with total autonomy, and yet, each arm is part of the animal. Offer this gift to that special someone.

Or some 3d silver tentacle earrings

Octopi are extremely romantic. After they mate, their life has no other purpose and ends. Let your love for her never end.

8 Biology-inspired Gift Ideas for your Valentine!

What’s love if not biology in action? This Valentine’s, say “you flood my brain with feel-good chemicals” to that one special other with these biology-themed gifts.

Cards, cards, cards!

All’s fair in love and war — especially the downright adorable, handmade cards from Tiny Bee Cards. Profess your love with the significant otter, let your S.O. know you’ll brave the rough seas of life together with this purposeful porpoise, or let your passionate side shine through with one very cuddly cuttlefish. Those are my favorite three, but their store is definitely worth investigating if you’re a fan of romance and puns — or if you’re looking to impress a foodie!


Buy on Amazon

Dopamine and Oxytocin necklaces

Reinforce your loved one’s affections with a dopamine-shaped pendant, or tighten the bond even more with an extra shot of oxytocin (also handily forged into a necklace). It’s all hormones, people!

Give ’em an STD they’ll love!

Just hear me out: PlushieSTD. Bouquet. All wrapped up in a cute, delightful bunch.

Done. You’ve just mastered Valentine’s.

STD bouquet.

Buy on Amazon

If you like the idea but you’re not sold on a plushie virus bouquet, they have a lot of other options.

Or at least some (rare, endangered) flowers

If romance rather than humor makes your better half melt, a more traditional bouquet might be in order. Cut flowers wilt and wither, however, and is that really the message you want to convey to your Valentine? Exactly.

So play the long game and show him or her that you two will only grow stronger with time, provided you stay hydrated — just like this Jade Vine (Strongylodon macrobotrys), a beautiful turquoise bonsai plant from the jungles of the Philippines, that you two will nurture together.

This isn’t any old flower — it’s a highly endangered, at risk plant. With its native jungles being cut down alarmingly fast, the love between you two could be what saves the species from complete extinction. It doesn’t really get more romantic than that. You get 10 seeds.

Organic chemistry scarf

Look closely enough and biology becomes chemistry. If your Valentine is hard at work studying in the field, this organic chemistry scarf will definitely let them show off their passion while staying comfy, warm, and stylish.

Tardigrades for him and her

Also known as water bears, tardigrades are ridiculously resilient — just like the two of you.

Seriously, these micro-animals have been found everywhere: from mountaintops to the deep sea; from mud volcanoes in tropical rain forests to the Antarctic, surviving in extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation. Now, you can wear them on your shirt, or even better — on your feet.

A hearty Valentine

We’re all used to the round, two-lobed heart as a symbol of love. Everybody will be generously slathering it in chats, messages, and cards for their Valentines when the special day comes. Let me ask you this, however: will any of those hearts have aortas popping out?

No! But yours will. Because you will show your love the right way, with this more anatomically-correct plush from I Heart Guts. If your significant other is into *ahem* correct biology, they will definitely appreciate it!

12 Perfect Gifts for Engineers on Valentine’s Day

If your significant other is an engineer, these Valentine gifts won’t fail to impress. Here are some gifts that will keep the wheels of love turning, at least until next year.

I love you Morse code bracelet

 Buy on Amazon

Nothing says I love you more than dot dot dot dash dot dot…

Love is about sharing a life together, and never letting go of each other when things become difficult. However, sometimes just saying I love you loses the intensity it’s supposed to convey, which is why this one-of-a-kind accessory is as special as your love is. Although you may have chosen to express your affection in a vintage communication medium, Morse Code will never go out of style.

A 3D Printer… for pancakes!

Let’s face it, most engineers don’t exactly treat their bodies as a temple. But how about you try something different for this year’s Valentine morning. Instead of cooking pancakes, here’s a cool idea: you print them!

An adorable pocket mirror that looks like a MacBook Air

An Engineer’s Valentine

I thought it’d be cool if I ended this post with an awesome poem written by Matthew Dalton. I’ll just leave it here for you.


I was alone and all was dark
Beneath me and above
My life was full of volts and amps
But not the spark of love

But now that you are here with me
My heart is overjoyed
You’ve turned the square of my heart
Into a sinusoid

You load things from my memory
Onto my system bus
My life was once assembly code
It’s now like C++

I love the way you solder things
My circuits you can fix
The voltage ‘cross your diode is
much more than just point six

With your op-amps and resistors
You have built my integrator
I cannot survive without you
You’re my function generator

You’ve changed my world, increased my gain
And made my math discreet
So now I’ll end my poem here
Control, Alt, and Delete

10 Perfect Valentine’s Gifts for the Chemist You’ve Got Chemistry With

Few things are as special as having chemistry with a chemist. If you want to show that special someone how much you care this Valentine’s, don’t lose your concentration. Here are some creative and special gifts which will certainly draw out a reaction.

Oxytocin necklace

Oxytocin regulates social interaction and sexual reproduction, playing a role in behaviors from maternal-infant bonding and milk release to empathy, generosity, and orgasms. Now, you can gift it to your love one as a necklace, too. The silver oxytocin necklace is stylish and elegant, but it also appeals to the geekier side of things. If you like the idea but oxytocin just doesn’t do it, or you’re just looking for a simpler necklace, you might want to check the dopamine necklace below. It’s also a bit cheaper.

Chemistry Valentine’s card

If you’d like something just a bit simpler, you can always go for the V-day card. But this isn’t just any old card, this is special-tailored for your chemistry-loving loved one.

Caffeine beaker mug

If there’s one thing chemists (and most scientists) love, it’s coffee. But why have your coffee from a boring old mug when you can have it from a beaker? No, not a beaker in the lab, you don’t know what’s been in there, John. Here, have this, it’s even got the markings and the caffeine molecule on it.

Beaker wine glass

We all know mornings are not necessarily the most pleasant part of the day, so maybe that’s not when you want your loved one to think about you. Love and wine go hand in hand, and with this glass, they also go hand in hand with chemistry. Now, if your Valentine is a bit more adventurous…

Chemistry cocktail barware set

I have to admit, when I first laid my eyes on this, I started drooling a bit. It’s not just that the set is chemistry-themed — and that let’s face it, who doesn’t like a good cocktail — but it’s made from high-quality temperature-resistant glass, too. It even has the hazard labels because, you know, dangerous things can happen once you start drinking cocktails.

If you like the idea but want something just a bit tamer, you’ll probably enjoy:

Chemist’s Spice Rack

Cooking is basically chemistry, but it can become much more interesting with this set. Everything is refillable, so you can use them again and again after the original spice has run out.

Caffeine necklace

If the oxytocin necklace is a bit too much but you dig the idea, here’s an excellent alternative: a caffeneine necklace. Honestly, when it comes to Valentine’s, you can’t go wrong with an necklace — and this is just the right mixture of science and love.

Chemistry scarf

If you’re not exactly convinced by what you’ve seen yet, or you simply want to go back to something simple but thoughtful, this is exactly what you’re looking for. After all, it’s one of the few times that chemistry feels soft and silky.

The Chemistry Between Us — Book

Lastly, what better gift than a book about the chemistry of love? The Chemistry Between Us is a fascinating book that takes a look at the genetics, brain chemistry and hormones that make love what it is.

7 Adorable Plushies for a Science-themed Valentine’s Day

When it comes to Valentine’s gifts, you really can’t go wrong with a plushie — but plushies can also be a bit generic and impersonal, and no one really wants that. So we’ve scoured the web to find the best and most unique plushies for this Valentine’s — and of course, they’re science-themed!

Fluffy Microbes of Love Bouquet

Love is in the air, and like a microbe, love thrives in warm, comfy environments. Guaranteed to make your Valentine smile, and then laugh — when they learn that the viruses here are Chlamydia, Herpes, and Kissing Disease. That’s right, you get to give your Valentine an STD bouquet, and they’ll thank you for it!

If that doesn’t work, then maybe…

Giant Microbes Heart Box

If this doesn’t win her over, then nothing will. Again, not only is this hilarious but it’s also incredibly cute. It’s pretty much the same thing as above (STDs included), though you get the chocolate version instead of the bouquet one.

Brain Cell

Okay, we all know that love sometimes bypasses the brain, but your Valentine will definitely fall in love with this one. What better way to say “I’m thinking of you”?

Realistic Octopus Plushy

Now, if adorable microbes just aren’t your jam, we’ve got you covered. We can dive into other options, like this rather upset, but still beautiful octopus plushy. Oh, and if that doesn’t convince you, then …

Maybe this Nautilus will. The Nautilus has been around since the times of the dinosaurs and continues to thrive to this day. It’s a living testament to biological endurance.

If you want the irresistible cuteness but would like something more land-based and relatable, then we’ve also got you covered. Who could resist this:

Stuffed Elephant Shrew plushy

Elephant shrews are not, in fact, shrews. Recent evidence suggests that they are more closely related to a group of African mammals that includes elephants. So they’re more related to elephants than shrews. There, that’s something you now know.

Water Bear Plushies

Nothing says “our love will endure forever” like a tardigrade plushy. Why, you might ask? Well, not only do tardigrades survive in any imaginable environment on Earth, but they can withstand scorching temperatures and even the frozen hell that is space. In plushy form, these micro-animals are also pretty cute, and bring a lot of symbolism to the table.

Fat… I mean chubby unicorn

I know, I know what you’re thinking — unicorns aren’t real, how can this be science-based? Well, let me ask you something: how can the tardigrade we were just talking about be real and the unicorn not? Besides, this unicorn’s had it rough. He broke his leg, was forced to give up on his sports career, had to take an office job, took a few extra pounds, his friends stopped calling him… he just needs a bit of love, OK? Just a bit of love.
