As he places his disks on the board, you can see them float from the repulsion force of the dimagnetism.  It looks like a futuristic game of air hockey.  I wonder if the famous Hover board shop Hendo Boards will try to incorporate this tech in future versions?

And this excerpt from wikipedia explains the potential of the force here

Diamagnets may be levitated in stable equilibrium in a magnetic field, with no power consumption. Earnshaw’s theorem seems to preclude the possibility of static magnetic levitation. However, Earnshaw’s theorem only applies to objects with positive susceptibilities, such as ferromagnets (which have a permanent positive moment) and paramagnets (which induce a positive moment). These are attracted to field maxima, which do not exist in free space. Diamagnets (which induce a negative moment) are attracted to field minima, and there can be a field minimum in free space.

A thin slice of pyrolytic graphite, which is an unusually strong diamagnetic material, can be stably floated in a magnetic field, such as that from rare earth permanent magnets. This can be done with all components at room temperature, making a visually effective demonstration of diamagnetism.
