Halloween is still some ways off, but that doesn’t mean you can’t prepare ahead of time especially with the $39 Broomba life-size Self-propelled Broom. It isn’t meant to keep your yard clean of leaves, but will automatically move around to scare whoever drops by thanks to a sound-activated mechanism. Whenever it moves around the room, it will play back haunting music while emitting frightful cackling sounds. Something tells me this will be a real hit during the upcoming Halloween, so you can’t say that you have not been forewarned!
