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 nervetoxin (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.
Challenge your friends to this Pterosaurs card game, and explore animals and plants that lived during the Mesozoic Era along the way. The game was co-designed with students in the Museum’s #scienceFTW program based on an existing biodiversity card game, Phylo.
Purchase or print the cards, play the game, and don’t forget to download the companion app which reveals animations of pterosaurs walking, flying, and more!
According to the laws of physics, a planet in the shape of a doughnut (toroid) could exist. Physicist Anders Sandberg says that such planets would have very short nights and days, an arid outer equator, twilight polar regions, moons in strange orbits and regions with very different gravity and seasons.
petition to turn the earth into a fucking doughnut
THE STORY POTENTIAL FOR THIS IS AMAZING YOU COULD HAVE TWO ENTIRELY DIFFERENT CIVILIZATIONS SEPARATED BY DESERT ON THE OUTSIDE AND AN PERMANENT NIGHT-WINTER ON THE INSIDE
YOU COULD (WITH A LITTLE FUDGING ON TIDES OR SOME STABILIZATION FORCE) HAVE MOONS THAT GO THROUGH THE FUCKING HOLE, WITH LUNAR-POWERED SORCERERS LIVING ON THE INNER EQUATOR IN GIANT ICE CASTLES WAITING FOR THE TIME OF THE MONTH WHEN THE MOON ILLUMINATES THE ETERNAL NIGHTTIME AND THEIR SPELLS HAVE THE MOST POWER
YOU COULD HAVE ENTIRELY DIFFERENT SPECIES THAT EVOLVED ON OPPOSITE SIDES WHO ARE BASICALLY ALIENS ON THE SAME PLANET AND WHOEVER CROSSES THE GIANT DESERT OR ARCTIC CIRCLE (HEH) MAKES FIRST CONTACT
THIS IS SO COOL
THIS IS SO COOL
I WANT TO RUN FIFTY THOUSAND GAMES ON WORLDS LIKE THIS HOLY FUCK
THIS JUST IN IF I’M UNDERSTANDING THE MAGNETIC FIELDS CORRECTLY I THINK THE ETERNAL NIGHT ICE REALM WILL HAVE NEAR-CONSTANT ELECTRICAL STORMS
Evacuating a sample of unknown fluid (to vaporize for mass spectrometry). Pressure drop causes a decrease in temperature. The fluid simultaneously both boils and freezes? Would like some insight here…
Edit: Thanks for the help guys. It appears we have found the triple point of the substance!
Edit2: The substance is Cyclohexane!
Watch this liquid boil and freeze at the same time! It’s not magic, these folks just dropped the pressure and temperature to the perfect place to hit the substance’s triple point, that magical nexus on the phase diagram where solid, liquid, and vapor coexist.
The liquid above is almost certainly not pure water (those crystals look a little funny), but here’s water’s phase diagram, complete with triple point and its various ice phases. Yes, even that one.
Fire glass produces more heat than real wood, and also is environmentally friendly. There is no smoke, it’s odorless and doesn’t produce ash. You are able to stay toasty warm without cutting down trees and the specially formulated glass crystals give off no toxic deposit.
A few months ago, physicist Harold White stunned the aeronautics world when he announced that he and his team at NASA had begun work on the development of a faster-than-light warp drive. His proposed design, an ingenious re-imagining of an Alcubierre Drive, may eventually result in an engine that can transport a spacecraft to the nearest star in a matter of weeks — and all without violating Einstein’s law of relativity.
BIG NEWS: This is the first time ever the genetic code has been fundamentally changed. The breakthrough is a huge step forward in synthetic biology and opens up the possibility of turning re-coded bacteria into biofactories, capable of producing potent new forms of protein that could fight disease or generate sustainable materials.
We are a superior species, we can fly faster and higher than eagles, swim better than dolphins, run faster than cheetahs and see in the darkness better than cats. We also use infrasounds and ultrasounds to see. But only when we do not use our infrared vision, when we do not sense the presence of other beings electrically or when we do not smell them from the several kilometers distance. We are superior.
Project Bumblebee (Conservation and Citizen Science)
In the late 1990′s, bee biologists started to notice a decline in the abundance and distribution of several wild bumble bee species in North America. Five of these species (western bumble bee, rusty patched bumble bee, yellowbanded bumble bee and the American bumble bee) were once very common and important crop pollinators over their ranges. Franklin’s bumble bee was historically found only in a small area in southern Oregon and northern California, and it may now be extinct.
The dramatic decline in wild populations of these five species occurred about the time that a disease outbreak was reported in populations of commercially raised western bumble bees, which were distributed for greenhouse pollination in western North America. The timing of this suggests that an escaped exotic disease organism may be the cause of this widespread loss…
