Description

Elegant, swooping hands pass 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 our 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.

Specifications:

  •     Beginner skill level – ages 12+
  •     Basic hand tools required (Phillips screwdriver, craft knife, wood glue)
  •     2 x AAA batteries required (not included)
  •     2 hour build time

  •     1 x GM3 Motor + battery pack
