Crankster
This “hands on” construction set includes over 100 pieces to build and create your own marble and gear run. Crankster includes a hand crank to move the marbles up the bucket and chain lifter mechanism to the top of the twisting and turning tracks. Once built, kids can watch their marbles drop, spin and roll through their own fun and exciting creation. All Techno Gears Marble Mania sets are interchangeable.
