Boyd Bushman antigravity recreation ThermoCap video part 1

I saw the Boyd Bushman antigravity demo video and decided to try it. Using the same 250 turns of 30 gauge wire, and 120 volts AC. Nothing happened. Then I tried varous voltages, AC (60 hz) and DC, and I placed the wire over mild steel, copper and aluminum. There was no significant lifting that I experienced. I’m slightly dissappointed. Maybe Boyd Bushman is using much more voltage or bigger wire. Louis Carroll
