Manual Marble Machine

The concept of marble machines has been around for decades, and the marble run, or rolling ball sculpture, has grown into an art form, with the kinetic sculptures featuring multiple overlaid tracks, switches and even musical instruments triggered by a trail of moving marbles.The machines themselves are complicated and essentially useless, save for as toys, providing a hypnotizing cycle of marbles around a track. The process becomes even more mesmerising where tinkerers and makers have added in electrical circuits, making reloading the run completely automated.By definition, a Marble Machine is a creative ball-run contraption, made from familiar materials, designed to send a rolling marble through tubes and funnels, across tracks and bumpers, and into a catch at the end.
