Have you ever dreamed of moving an object with the power of your mind? Mindflex, the new mental acuity game from Mattel, makes that dream a reality! A lightweight headset containing sensors for the forehead and earlobes measures your brainwave activity. When you focus your concentration, a small foam ball will rise on a gentle stream of air. Relax your thoughts and the ball will descend. By using a combination of physical and mental coordination, you must then guide the ball through a customizable obstacle course-the various obstacles can be repositioned into many different configurations. Mindflex combines advanced technology with the power of thought to create an interactive experience unlike any other - a game where players compete in the ultimate mental marathon! For ages 8 and up. Requires 4 'C' and 2 'AAA' batteries.
