Sonic teenager repellant

29Repelle.1841This guy invented a device that he says emits sounds only young people can hear – it’s used to chase them away and stop them from doing bad things. Nooo!! Not the Ludwig Van, and the dreaded Ninth Symphony! “Howard Stapleton, inventor of the Mosquito, with a speaker mounted on the wall behind him, at a store in Barry, Wales, where boisterous teenagers once gathered. The device projects a very shrill and very annoying tone that only youths can hear. Then they flee.” Thanks Nick! Link.

  1. The high-pitched whine might repel teenagers well, but I bet it will attract rocks.

    In fact, I bet rocks, bricks and other debris will be so attracted to the whining storefronts that they’ll smash right through the windows trying to get closer to the source of that wonderful sound.
