A science teacher wanted to teach his 5th grade class a lesson about the dangers of alcohol, so he produced an experiment that involved a glass of water, a glass of whiskey, and two worms.
“Now, class, closely observe the worms,” said the teacher while putting a worm into the water.
The worm in the water writhed about, happy as a worm in water could be. He then put the second worm into the whiskey. It curled up and writhed about painfully, then quickly sank to the bottom, dead as a doornail.
“Now, what lesson can we learn from this experiment?” the teacher asked.
Little Johnny raised his hand and responded confidently, “Drink whiskey and you won’t get worms.”
