Chemistry Class
Published Feb 14, 2003
During class, the chemistry professor was demonstrating the properties of various acids. "Now I'm dropping this silver coin into this glass of acid. Will it dissolve?"
"No sir," a student called out.
"No?" queried the professor. "Perhaps you can explain why the silver coin won't dissolve."
"Because if it would, you wouldn't have dropped it in!"
