CD Hovercraft

A cd with a piece of paper over the hole of the cd and a balloon as well.
PIRA 1F30.12

Materials: CD, Balloon, Small Spool, Paper

A cd has a piece of paper glued to it covering the hole, to which a small spool is then attached. Air is pushed through a small hole in the paper by a balloon attached to the spool. A small cushion of air allows the CD to 'hover'. Please note this works best on smooth surfaces.
