Stupid science questions


Just a few random things I wonder about from time to time, but never seem to get around to solving:

  • Rain on the Windshield: Presuming the rate of rainfall to be constant, will there be a difference in how much rain strikes the windshield of any given car depending on whether it is stationary or moving?
  • Wet T-Shirt Contest: Why does a white cotton t-shirt become nearly transparent when it gets wet?
  • Kool-Aid: Why do different varieties of Kool-Aid juice mix dissolve at such different rates? I’m thinking here of why orange-flavored Kool-Aid appears grainy so much longer than fruit punch or grape.
  • Frozen Soda: Does the color of a liquid affect its freezing temperature? Or what properties contribute to orange soda freezing more easily than root beer or cola?

Minutiae, of course. But I think the T-shirt question would probably keep a high school student’s attention. Well, the guys, at least. The hetero boys, that is.

Never mind.
