5/8″ ball bearing playground

This kinetic sculpture is a ball bearing’s paradise. Not only do they get a cushy ride around two lift wheels but there’s a variety of enjoyable obstacles they can go down. The first is a vortex made from a wooden flower pot which sends the balls randomly down one of two possible exits. From there it’s on to enjoy a ride on a flip-flop, a divide-by-three (takes weight of three marbles before it dumps them all), a zig-zag track, or a divide by twelve mechanism. We’re sure this is a riveting read, but don’t miss the video after the break where [Ronald Walter] shows it in action and takes it apart to illustrate the various features.

If you’re wondering about the digital logic terms used, we’ve seen wooden devices that use these concepts in the past.

    Love these! Like playing mousetrap as a kid.

  2. @JC LOL you know my brother worked for FAG bearings and had this name tag that had to be visible at all times. So there was a nice close up picture of his face with a huge red FAG right above it… I loved it :)

  3. @Caspan – I hoped somebody would get that! I actually used to work for Timken, so that was always pretty funny to me. I’m sure it means something way different in Germany (I think that’s the right country).
