This project was tough. working with bouncy balls are a pain in the butt! anyway, here is a project I made in about three weeks. It has two lifts and a looping path as well as other paths. I made the pictures big and clear enough for people to try to copy it, that's what I do or try to do on other's photo instructables. The video shows some flaws in the model but they are bouncy balls, they don't care.
