Revolutionary Demonstrations

Some of the most interesting demonstrations that you can do in ZeroG revolve around conservation of angular momentum.  If you've got a spinning mass, you can do all sorts of cool things.

The trick is to get a really good spinning mass on the airplane within the rules.

Fortunately, there is a really good angular momentum source within reach of just about everyone reading this entry -- the hard disc in your computer.

So the plan is simple: stick an old (preferably high-rpm) disc drive into a cheap USB enclosure, and replace the wall-wart with a 12v battery.

Planned demonstrations: conservation of angular momentum (turn on drive, it spins one way, operator spins the other) and gyroscopic precession (spin up before we hit zero-g, then tilt the drive enclosure)

As always, your suggestions for improvements and additional demonstrations are appreciated.
