Levitation

I just saw someone almost-levitate. What happens is this: four people try to lift one person with four fingers each. It doesn't work. Then they all stack their hands on top of each others and push on the person's head. They count to nine, while pushing, and then quickly put their four fingers back into place (four fingers under each knee and under each arm). They then try to lift the person up, and it works! they lift them really high! It's crazy. I don't like it. It sort of freaked me out. I didn't participate, it seemed... unnatural.
