Marble Run Chain Hoist What is it about marble runs that makes them so compelling? Kids (and adults!) can watch marbles going down a track, passing through various obstacles, for hours on end.  Marble runs are fascinating, they grab our attention, and yet they're also relaxing. You choose a marble to watch, to cheer for, you wonder which path it will take, you put yourself in the marble's place, imagining that you are right there with the glass ball, going on a marvelous, unknown journey, with twists and turns and surprises around every corner. The thrill is even greater when you've built the marble run yourself. Now you're not just passively watching a video, you're fully invested because you built a wondrous machine with your own hands.
