@TamoanBoy Something like this, yes. But not nearly as nice and smooth. In the future I will be building Coin-op machines, no gumballs though. Too messy, and the gumballs are not very round - so the tracks have to be overly simplified.

I wonder if it would be possible to curve the end piece up to the top again so that it uses the spiral as momentum and just keeps going. I mean, you'd obviously have to take into account the forces of friction, gravity, and wind resistance, but I think it'd be possible to keep it going for quite some time.... It'd be a cool experiment to try.

The marble just loses too much energy on it's way down, especially on something that's 3ft tall. BUT...I have seen where someone used the energy of the marble when it reaches the botton of the run to release another marble at the top. With a long row of marbles queued up you could keep it going for 30 minutes or more... : )
