Little Johnny, after a science lesson on the laws of gravity, returned home, determined to prove his teacher Mr. Knowles wrong."Not everything that goes up comes back down, and I'll prove it!" After some brainstorming, he placed a bowl of water in the 12 PM, windless, Sunday sun, and watched as it evaporated. "It all went up," he said. The next day at school, he confronted his teacher about his little science project. But Mr. Knowles told Little Johnny that he was a bit short-sighted. How so?
