Chemistry Class A chemistry professor wants to teach his students about the evils of alcohol. So he designs an experiment that involves a glass of water, a glass of whiskey, and two worms. “Now, closely observe the worms,” says the professor as he puts one in each liquid. The worm in the water writhed about, happy as a worm in water could be. The worm in the whiskey writhes about in pain, then curls up and sinks to the bottom of the glass dead. “Now, what lesson can we learn from this experiment?” the professor asks. A wag at the quickly raises his hand and says, “If you drink whiskey and you won’t get worms.”
