I'm surprised they don't shatter when they run into each other.

@Supermassively Over time they chip.... that's why i switched to the mini billiard balls... less noise too. Bonus!

I was wondering where you get the motor to attach the spiral lift to? I'm doing a roller coaster project in physics and I want to make it go on forever but I don't know where to get that motor for the lift. Can you help me?

Thanks.
