U.K. inventor Howard Stapleton came up with a novel device for keeping rowdy teenagers from loitering in front of stores. He calls the teen-be-gone gadget, which emits a high-frequency sound that adults can't hear, The Mosquito.
"It's small and annoying," Stapleton told The New York Times. The Mosquito's irritating buzz supposedly can be heard by almost everybody under 20 years old and by almost nobody who's over 30.
A South Wales store owner, who attests to the device's effectiveness, says he was about to install loudspeakers to pump classical music into the parking lot to help disperse troublemaking teens, but the Mosquito does the trick nicely.
