An instructor in chemical warfare asked soldiers in his class: "Anyone knows the formula for water?" "Sure. That's easy," said one man. "What is it?" "H, I, J, K, L, M, N, O." "What, what?" reasked the instructor. "H to O," explained the chemistry expert.
If H2O is the formula for water, what is the formula for ice? H2O cubed.
Since the bartender is not a chemist, he has no idea that H2O2 is the chemical formula for hydrogen peroxide, and gives both chemists a glass of water. Expecting that one to end a little differently, too? If you’re unfamiliar, this is the (rather dark) way that joke usually ends. Plus, check out some more brainy and hilarious science jokes.
