1. In the video, they push the disc with a pen until it rolls over. They repeat it multiple times. It it were superconductive they could just position it in space without laying it on the magnets first.

2. The disc is not hovering.

3. The disc is damaged; one edge is thicker/heavier than the other. Thus causes the rolling. Notice that the heavier part always stays on the magnet. It it were superconductive they would be able use a uniform disc.

I call BS.
