This seems like something right out of a comic book. But it's for real, and you're going to love the sound of it--a sonic deterrent that repels that portion of the demographics which thrives on being whinny and grating to adult nerves. That's right, we're talking bratty teens under 20. Nicknamed the mosquito, the gadget, invented by Briton Howard Stapleton, apparently emits a shrill noise audible only to this particular age group. Adults lose that ability as they age. The noise is annoying enough to have teens clutch their ears and move away from the source, and is said to sound like a demented insect or a very badly played violin. Quick, someone send this to Supernanny.
