Room Defender Sentry Turret
Why didn’t they have these things when I was growing up? The Room Defender (thanks, Gizmodo) is a motion detector-equipped, foam disc-shooting cannon mounted on a tripod. When someone enters its view, it issues a verbal warning. If the intruder doesn’t leave, it bombards them with foam discs. There’s even a remote control that you can use to manipulate and deactivate the device. Also handy for keeping your dog off the livingroom couch.
