Street performer in "levitation" act, seems to be floating in the air.
This is "Special Head" (Danny Wolverton), and he was performing this classic levitation act extremely well.
For more info, see his facebook page www.facebook.com/pages/Special-Head-Danny-Wolverton/23192...
I found it quite sad that adult people in the US, supposedly educated (including in science), actually believed that he was using his "mind power" to levitate. Or maybe everyone in the audience was high on drugs?
