Mindflex is a toy by Mattel by which, according to its description, the operator uses their brain waves to steer a ball through an obstacle course. Brain waves are registered by the enclosed EEG analysis headset, which allows the user to control an air stream by concentrating, thus lifting or lowering a foam ball that is trapped in the airflow due to the Coandă effect.
Controversy
Despite the science behind the technology developed by Mattel, outside scientists have questioned whether the toy actually measures brain waves or just randomly moves the ball, exploiting the well-known illusion of control.
