Flycatcher Mark II
Instead of tiki-torches for your next outdoor barbecue you can pick up one or two of these battery-powered Flycatcher Mark II venus flytraps which use a chemical-free bug bait to lure the critters into its waiting mouth. Once there, a sensor is triggered and the jaws snap shut, squishing the little pests, and totally Little Shop of Horrors-style, it also has the option to let out a belch whenever a fly is devoured. Fortunately the makers realized this would get really annoying, really quickly, and added the ability to turn the sound off.
