Today my group put the cup onto the maglev. We put 19 marbles in the cup until it fell on to the track because it was to heavy. Then we put a track in the middle so it could support more weight. Here are a couple of pictures.

At first we used a bunch of tape to hold on the cup. But that added a lot more weight. So then we just let the cup rest on the maglev. It actually worked a lot better than before.
