They took a big clear plastic storage container and set it over top of the wheel. The container was positioned such that it overhung the countertop slightly, which allowed us to get our hand and arm inside to experiment. This was a way of controlling for ambient airflows that would be capable of impacting the device.
I've used the device with Faraday cage lined gloves on before. That was interesting.
The thing with the heat theory is that the heat theory doesn't account for the fact that sometimes the wheel will flow "out" and sometimes it will flow "in". Define outflow as the wheel's direction of motion along your hand is away from the palm/wrist/arm and inflow as the wheel's direction of motion along your hand is towards the palm/wrist/arm.
Sometimes, the same hand will give me in flow or out flow. If it was heat transfer driving the wheel, the wheel should only rotate in one direction for either hand. I thought about this by analogizing a 1 pipe, load-match heat pump HVAC system to the vascular system in the hand and fingers especially but I can't say the heat theory has any traction.
