I love how this post is like “Oh, clean up some of the nastiest, hard to clean shit with coke!” but doesn’t mention “Hey, you actually ingest this stuff that can clean CORRODED CAR BATTERIES.”
Heyyy this is because when you put carbon dioxide to make the carbonated water, you get carbonic acid. Carbonic acid varies in how much the pH is, especially in the different coke products. Strong enough to dissolve rust but not steel or any of the metals mentioned here.
But here’s the thing, carbonic acid is not one of the 6 strong acids. You know what is one of those? Hydrocholric acid. You know where you naturally secrete hydrocholric acid? Your stomach. Hydrochloric acid is some nasty stuff and WILL eat away at a screw if allowed to soak long enough. If you ever got just drop of a diluted solution on your skin in chem lab, then you can see where that would happen very easily.
The stronger acid wins. Your tummy is fine when you drink coke. Your tummy makes acid strong enough to fuck that corroded battery up. It can handle a can of coke. Please don’t swallow a screw or something to test this tho, please.
thank you science side of tumblr <3
Seriously. You could probably do all of these with lemon juice (citric acid) or vinegar (ethanoic, or acetic, acid) just because acids work in pretty similar ways. Actually, when you see people recommending vinegar as a household cleaner? This is what it’s doing!
Also, as someone who has accidentally inhaled hydrochloric acid fumes, TRUST ME, THE CARBONIC ACID IS MUCH BETTER.
Every time I see a hysterical post on modern food I just kinda point and laugh
Because dude. Dude. You know what you breathe in and out every fucking second to survive? Oxygen. An incredibly corrosive gas that is probably responsible for more deaths across the history of the planet than anything else. Not only that, it’s a biproduct of photosynthesis. You literally rely on plant excretions to survive
Do you know what most of your body is made up of? Water. Which, given enough time, will destroy anything.
That morning coffee you like? Well shit, caffeine - lifeblood to many - is actually an incredibly potent nerve toxin (If you’re an insect). Plants actually produce that shit as an insecticide.
That refreshing zing from citrus? Acid. That juicy smack of a tomato? Acid and cadmium. That tart in an apple? Arsenic. That seasoning you put all over your fish and chips? Acid strong enough to destroy seashells - life that has evolved to survive living in a salt-drenched sea.
Stop being a tit and drink your damned coke.
EVERYTHING. IS. CHEMICALS.
It IS safe to say though that drinking/eating too many acidic foods CAN damage some things such as the esophagus or teeth - but it does require QUITE a lot of acid.
Well, the rust thing only works with coke. Any other acid will make it worse. The phosphoric acid will create a thin layer of Iron phosphate and that will save any iron metal from further rusting.
Something I realised, after having to help many international tourists count out their change, is that American coins don’t actually have the number value on them??? Like no wonder all these poor tourists are so confused
it just fucking says one “dime”
what the fuck is a dime
how much is it worth
whose idea was this
oh my god i never even realized that what the hell we all just sort of know what they’re worth through some sixth sense bullshit

I think any non-potterhead just went “What in the fuck?”
there is no such thing as a non-potterhead on this website
Hello, non-potterhead here! Never seen nor read Harry Potter! Seriously, yes, never.
Episode 13: Unafraid of the Dark, Cosmos: A SpaceTime Odyssey
That is fucking frightening.
This is fucking inspiring and beautiful. This is science. Never assume you know everything. Never assume you have all the answers. Life is vast, the universe is diverse, forever expanding, and mysterious. Life is amazing and literally everything in existence is a miracle. We are in the Universe, but we are also made OF the universe so we are in the universe while it is also a part of us. Stars had to die to create life, we literally are made from dead stars. This shit’s amazing. Does it have the potential to be terrifying? Sure. But I find religious ideology to be much more terrifying. Science is spiritual. Science gives me perspective. Science astounds me. Confounds me. And life itself is beautifully vast and reproducing itself everywhere, expanding for eternity. That’s spiritual right there. And it’s also science.
