Hovercraft construction



I'm getting pretty excited about the idea of teaching mechanics
and building the ideas of inertia, circular motion and Newton's laws
using student-ridable hovercraft built with plywood. Arons discusses
the use of 50kg block of dry ice on glass to kinesthetically
experience inertia; I think the homebuilt hovercraft is the way to go,
easier to get and far more intrinsically motivational (fun & cool).

Having said this, I've have to admit I've never personally build a
homemade hovercraft. Does anyone have experience building these
things they could share with me? What airtrack sources? What
designs?

If successful I think we'd build several dozen as part of a teachers'
alliance and or summer academy course project.

Your suggestions are sought and welcome.
