Mindflex is a toy by Mattel which apparently uses brain waves to steer a ball through an obstacle course. The brain waves are captured with the enclosed EEG headset, which allows the user to control an air stream with their concentration, thus lifting or lowering the delicate foam ball.[1] The game was released in the fall of 2009.[2]

Scientists have questioned whether the toy actually measures brain waves or just randomly moves the ball, exploiting the well-known illusion of control.[3][4] However, despite the Spiegel/Haynes experiments, supporters of the game believe that the headset does read EEGs (it uses the same chip as the MindSet from NeuroSky and has been used in homebuilt EEG machines).[5]
