Transparent Perpetual Motion Marble Machine

Here is another cool marble machine with an electromagnetic drive that keeps going without human interaction. Once you drop your ball from the top, it will go through the track and is pushed back to the top. It has a rechargeable battery and ships with 10 balls.

This motorized marble machine comes with a simple touch button that you can use to turn it on. It has a transparent shell, so you can see what’s inside. Other colors are also available. The above video shows how the black version works.
