Birthweek Wishlist: Mind Duel

In Harry Potter, a wizard's duel involves two wizards and their two wands, flinging spells left and right. But for Harry Dresden, a wizard's duel involves a ball of death being pushed back and forth using only the Will of the two wizards. The one with the weaker Will ends up kapoofed when the ball of death touches them.  Nobody's going to die using the Mindflex Duel, but it's a similar mechanic. Strap on the headbands and challenge a weaker minded friend to a duel. Mindflex uses a variation of EEG technology to read the intensity of your brainwaves. When you concentrate, the ball rises. When you relax, it sinks. Force the ball into your opponent's end zone to win.
