Here’s a little high-tech prank you can play on your friend’s home theater this year for April Fool’s Day. It is the TV Poltergeist.
All you need to do is hide this device in the room, and make certain that the LED is pointing straight at the TV. This will start a process where the television will turn off every 5 to 20 minutes.
Oh man, is this going to spook your friend or what?
