The Solarbotics GraviTrack Marble Machine Kit is part of the Marble-Drop mechanism family. Its swooping arms pass the marbles to each other to the top of a sweeping multi-level track. A switched battery pack smoothly exercises the mechanism. The smooth pick/hand-off/place motion is hypnotic and enchanting. No soldering is necessary.

Measuring approximately twice as wide as the original Solar or Battery Marble machine kits (at 250 x 127 x 140mm, or 10" x 5" x 5.5"), the GraviTrack is still desk-top compact but large enough for easy mechanical assembly.
