31" high X 17" wide (at widest point). 100% welded Stainless Steel. Will never rust! And can be cleaned easily - Dishwasher Safe! 

NO motor - NO power needed! Take this fun kinetic marble run wherever you want. 

Semi-Automatic operation is fully gravity powered. Place up to 50 marbles in the queue at the top. Press the handle to release a few onto the tracks and when each marble reaches the bottom, they push the handle and release another ball from the top.  This continues until all of the marbles in the queue have been exhausted. Reset them by hand, and watch them go again! 

Three different tracks have tons of fun elements. There are 3 sections of horizontal zig-zag on track one which also has surprising turns and corners.

Tracks 2 and 3 are fed from the metal plate, and will take one of the two paths randomly. The metal plate is fed from the marble collector. The marble collector is adjustable so you can choose whether it tips with every ball, or saves up 2,3 or 4 balls before tipping them together to choose their path on the metal plate.

Track 2 has 2 sections of fast spirals. Track 3 drops directly into a tall zig-zag. 

Couple of fun surprises that only happen occasionally; When two balls roll through the fast spirals - sometimes they are too close and one ball fails and falls to the bottom of the spiral. I added some spiral chutes that direct the ball back onto a lower track, keeping the balls rolling smoothly - this only happens once in a great while.
