If you are a lover of building your own machines that can do whatever your imagination can think of, then this is something that you have to get. You will be mesmerized as the ball goes around the track that you build for it. The auger that lifts your ball back to the top will ensure that it is in constant motion, flying down the track to its next turn or looping through the track again and again. This item will glow in the dark.
