Another neat electrostatic demo is to take a 3 ft pvc rod, some silk and
then cut a strip off of a grocery bag so you have a ring of plastic
about a foot or so in diameter (whatever diameter the bag is) and about
1" wide. rub the rod and ring with the silk and you can float the ring
above the rod. If you make a few, you can have races.
Of course, if she can get it, nothing beats LN2 at a party!
