ITS NOT HEAT THAT DOES IT!!!! check out this video on youtube, this guy shows that heat and other things do not effect the psi wheels.
Scientists will tell you that the warmth of your hands causes the air on that side of the wheel to heat up; since heat rises, the warm air goes up, creating an upward current that spins the psi wheel. Try getting your hand warmer by cupping your hands on your mouth and blowing, then immediately try to rotate the wheel. Does it work better that way? Try sticking your hand in the freezer, then rotate the wheel. Does it work?
