Burglar Blaster

Worried about thieves raiding your home while you're on vacation, at work, or just passed out in the backyard? Then booby trap your house, Kevin McCallister-style, with the Burglar Blaster ($600). This self-contained unit uses a passive infrared intruder detection system to monitor areas up to 2,000 square feet, and releases an eye-destroying 4 oz. of pepper spray when triggered. It offers an adjustable entry time delay, a cast aluminum/alloy case, can run for years on a single set of C batteries, and will only help reaffirm your crippling paranoia.
