Magic Tricks

the idea is good, the materials not so, why black sponge balls and not yellow/red/green as the original? If the black ball is at the bottom in the clear tube it is almost invisible because the black stand. The balls are to cheap and hard, I changed the black by red soft ones and added a yellow soft one. So I can do the traffic light routine. The tube is made of very thin plastic and deformed already because the string inside it.I also made an extra something to the base so the load is completely invisible. Good idea, but needs more improvment.
