This is a kinetic sculpture that catapults ping pong balls into the air, into a basket, and back to the catapult. It runs for as long as you want it to with a motor, and a rubber band powers the catapult. A mechanism at the end allows each ball to load into the catapult one by one. It's a useless machine, but fun to watch. :-)
This machine is made to use 38mm ping pong balls.
Here's the video of the ball juggler in action:
So, let's get building! I hope you like it!

If you have all of these pieces, then you may begin! If you don't, then you could still try, and leave some pieces out (even though it won't work as well). Tan (red rod length) or black (gray rod length) rigid rods can be replaced with red or gray rods.
