Toy companies are always pushing products designed to make kids use their brains. Mattel has taken things one step further at CES this year, with the introduction of the Mind Flex. On display this week at the Sands Hotel and Casino, the toy scans players' brains to move a little floating ball across the game board.

Player but on a battery control headband, controlling the height of the ball by concentrating on the object. A little wheel on the board is turned to advance it along the board. The goal is to get the ball through various objects.

Mattel told us that the game will be available in fall for about $80.
