Steve Spangler Science: CD Hovercraft

Here’s a miniature, homemade version of a hovercraft that rides on a very thin cushion of air.

The puck used in an ice hockey game is designed to be nearly frictionless as it flashes across a surface of ice.  At a game center, “Air Hockey” uses air blowing upwards from hundreds of tiny holes in a surface to keep a puck nearly frictionless as well. In both games, the whole idea is to defeat friction and to move very quickly in any direction. Now, you can build your own air-riding hovercraft to do that very thing.
