Coke blows balloons:
Take an unopened bottle of coke. After opening the bottle cap, put the balloon on the bottle mouth and let the baby shake it hard, and the balloon will slowly "blow".
Experimental principle: Coke contains carbonic acid, which will decompose the gas that produces carbon dioxide when it is shaken violently. Coke gives off a lot of gas, and the balloon on it will expand ~
Cola (English: cola) refers to a carbonated drink, which is sweet, with caffeine, but without ethanol.
Flavors include vanilla, cinnamon, lemon and so on. The name comes from one of the early materials of cola: cola fruit extract. The most famous cola brands are Coca Cola and Pepsi Cola.
Drinking coke is a consumption behavior that is no different from drinking other drinks. However, the rich cola culture goes far beyond the category of "drinking drinks".
Invention:
Coca-Cola was invented by American pharmacist john pemberton. He hopes to create a medicinal mixed drink, which can refresh, relieve fatigue and treat headaches. Pemberton's "Cococola" was originally gasoline-free. It was mixed with cold water. It was only because of an accidental accident that it became a carbonated drink. 1On the afternoon of May 8, 886, an alcoholic stumbled to the pharmacy in pemberton.
Say to the clerk, "Have a cup of medicine for headache and brain fever." The clerk was supposed to go to the faucet to replenish water, but the faucet was more than two meters away from him, and he was too lazy to walk around, so he picked up the soda water nearby and mixed it with Cocoa Calari. As a result, drunkards actually like it. He drank one cup after another and kept saying, "It's delicious. Delicious. "
Alcoholics also advertise the magical effect of this non-alcoholic drink everywhere. Before john pemberton died, they sold the patent right. Forty years later, people all over the world knew about Coca-Cola. A carbonated soft drink containing cola nut extract and other condiments originated in the United States.
But coke contains caffeine, which is harmful to human body, but also beneficial. Everyone knows that coke contains carbon dioxide. When carbon dioxide burps in the human body, it will take away the heat of the human body and dissipate heat.
