And now for something completely stupid:
This troper does what she calls "experiments", which are really just doing random/stupid things to see what happens, such as dropping a grapefruit in a shoe (using my sock as insulation) off a flight of stairs to see what happens. (If you're curious, the grapefruit cracked, and I got a sticky sock.) The "control group" the next day consisted of dropping an unwrapped grapefruit off of the same stairs (it didn't crack); it was more an excuse to drop things off of heights than any attempt at scientific accuracy.Â
