Abstract
Abstract A toy vehicle and a track are provided on which the toy vehicle travels. The track is composed of connectable track components forming a guide surface for the vehicle, a conduit which can be connected with a source of gas under pressure, and a plurality of uniformly distributed pin-hole openings which communicate the conduit with the surface so that the compressed gas which escapes through these openings forms a gas cushion above the surface on which the toy vehicle can slide.
