If you click on his first video (this is the second), he tells you how it's done:

Both videos made use of the same gimmick, a trick table. That being said, however, still none of those things I listed above were used in this trick table. In the first video, a pin sized hole was drilled in both the surface of the table as well as the plastic bowl the set up was sitting on. From there, a person off camera was blowing into a tube that was connected to this hole (under the table) which cause the wheel to spin. The second video used this same principle, but in a more sophisticated fashion. The surface of the table is hollow, with two separate air channels going to two different pin holes. Two tubes could "plug in" to each hole on the hollowed legs, which were hidden by thin layer of laminate that could pop on and off. This is why you can't see the bottoms of the two front legs on the video when the wheel is spinning. And again, I used an "associate" to plug and unplug the tubes as well as to blow into them for a more convincing illusion.
