I know some of them. And let me tell you, some of the people I know have nothing resembling the abdominal strength to do it. There are sometimes cases of brief hoving with that technique, although it is very uncommon.
Atleast it is better than 50% of people who think they have TK abilities. I have seen psiwheel videos, and they could easily be total BS. I built a psiwheel, and just by modelling the physical motions the TKers made in videos I made the thing spin. I actually found that small motions move it better than big ones. Like slightly moving my index finger for 30 seconds will turn it, but quickly moving my hand will just wobble it.
