When I was in first grade a bunch of friends and I thought it would be a good idea to get up on our roof with garbage bags... plus an extension cord attached to a hair dryer. You can see where this is going, i'm sure. We basically thought we could use the hair dryer to fill the bags with hot air and float gently to the ground. How we didn't break any limbs, I don't know.

Anyone else try various flying machines? I remember cardboard wings, experiments with bikes with wings, etc.
