Another terrific example of my “basic” desktop. Two tracks that are fed by marbles when you push the lever. So, load the marbles into the top queue, and release as many or as few as you like onto the two tracks. Track one is the loop d’ loop. When the ball exits the loops, the ball’s own backspin slows it down quite a bit. Fun effect to watch. Track two has a bunch of cool elements. See 3 separate sections of zig-zag track, a tipping arm, a flat spiral and lots of great twisty tracks that connect all of the fun ball tricks. They two tracks meet head-on at the bottom for some great action right at the end.
