When we were kids a friend and I found an old soccer ball, filled it with rocks and gave it to my older sister to kick. At first we cracked up laughing but then we had to ruuuuuuun really fast.
In elementary school I absolutely hated chemistry. Hated it!!! But now and then I learned few useful things, such as how to separate oxygen and hydrogen. So I did it at home, collected a test tube of hydrogen, walked quietly to my older sisters room when she was there, put a match under the test tube. The resulting bang was really, really loud and would scare the living daylight out of my sister. She would beat the living daylight out of me but it was soooo worth it :-)
