Prank a friend with this clever wireless interaction. A pressure sensor on the bottom of a chair leg wirelessly transmits a signal to a servo-activated light switch. When your friend sits on the chair, the lights will go off. When s/he gets up to turn the lights back on, the lights turn on on their own… and so on. Sit back and watch hilarity ensue.
