Don't waste your time using a dry ice puck. If you want an excellent piece of

This small hovercraft, about 9" OD, comes with NiCd batteries so you won't
have to go
through the hassle of buying dry ice every year. This thing also hovers
above carpet,
not the thick shag carpet, but the low loop carpets you see in most commercial
applications.

If you give this thing a kick in the hallway, it will travel to the end of
the hall,
bounce off the wall and come most of the way back. This is way cooler to
play with
than the dry ice puck.

How 'bout those hovercraft we made at a regional AAPT meeting a couple of
years ago? The students can ride them. That's kinesthetic learning!
