This is the game that uses your focused brain waves to maneuver a ball through an obstacle course. A headband and two earlobe clips measure theta wave activity produced by your brain (similar to EEG monitoring technology used by medical professionals). As you relax and concentrate, the headband sends a wireless signal (based on your mental commands) to the game's air fan, which increases or decreases its speed, suspending or lowering a foam ball; a knob enables you to turn the gameboard in order to move the ball through one of eight obstacles, including hoops, teeter-totters, baskets, or chutes. The obstacles may be interchanged; includes nine total obstacles. Requires four C batteries and three AAA batteries. Ages 8 and up. 15 1/4" L x 10" W x 5 1/2" H. (2 lbs.)
