Foam snakes, or elephant toothpaste, is a pretty simple chemistry demonstration. It takes nothing more than a container, a little dish soap, some yeast, a bottle of hydrogen peroxide, and perhaps just a touch of food coloring, if you want to get decorative. What i

Unfortunately for it, it cant do you any real harm, other than getting soap in your eyes, which is why it is demonstrated in classrooms the world over. The chemical formula for hydrogen peroxide is H2
stanley cup O2. Thats water with one extra oxygen atom attached to it. Putting in dish soap and food coloring liquid doesnt do anything to the hydrogen peroxide. Putting in yeast does. It starts off a process that goes at a rate of about 200,000 reactions per second. Inside the yeast is an enzyme called catalase. The enzyme, along with an extra oxygen atom, rips an oxygen atom off the hydrogen peroxide molecule, leaving oxygen gas and H2O, or water. The extra oxygen atom is that has just been freed up helps in another reaction and the whole thing spreads. Whats left is a lot of oxygen gas and wa Vnas Six Things Your Friends and Family Should Have Gotten You From Amazon
How did smooshing our faces together come to signify love and affection As we ;ve written about previously, one of the most compelling explanations hinges on the practice of mouth-feeding 鈥?the passing of pre-chewed or regurgitated food from the mouth of one animal to another. Lots of species, including humans, are known to mouth-feed. But when and why did we make the leap from mouth-to-mouth feeding to full-blown makeout sessions Where Did Kissing Come From In the latest episode of VSauce, Michael Stevens runs us through a slew of fascinating studies wi
