Air track

Air track

:"The Air Track may also refer to a breakdance move.":"See also AirTrack for other uses."

An air track is a scientific device used to measure uniformly accelerated motion and determine gravitational acceleration. Its name comes from its structure: air is pumped through a hollow track with fine holes all along the track that allows specially fitted air track cars to glide relatively friction-free.
