Not quite. The real power of the band is fleecing suckers of their money. Here's the cliffs notes on the grab 'em, scam 'em balance trick.
W/O bracelet on (follow along on the informercial and it always plays out the same) - grab the test subjects arm when they aren't expecting it, pull hard straight out to the side, the victim caves under the lack of awesomeness without the magic bracelet of Narnia
Bracelet on - Let the guinea pig know that you are about to pull their arm, watch as they stabilize in anticipation of it (kinda natural to not want to be pulled to the ground), big guy doing the test pulls straight down on the arm with equal or less force this time. Combination of broadcasting your intentions, plus pulling in a direction that couldn't fell an intoxicated Kate Moss = the magical power of harnessed energies
Truly amazing shit.
