I'm working on this one right now and it's completed except for cleaning the tracks of their weld stains. This is a three track motorized tabletop with 1" glass marbles. Select one of 5 speeds to enjoy watching the marbles speed down the tracks in a mesmerizing show of physics.
Watch the ball travel through the Loop d' loop and the tall skinny spiral at fantastic speeds. See the tipping arm, horizontal zig-zag track, "marbles on track" element and the flat spiral all connected together with curvy fun tracks. All three tracks merge back together at the bottom to get in line for the automatic chain lift so they can take another trip down the stainless steel tracks.
Don't let this tabletop Rolling Ball Sculpture get away before it's gone!
