This Mosquito makes unruly teenagers buzz off

Awesome, a device that only affects teens and makes them go away. No pain from Mace or a lawsuit from a Taser.
The device, called the Mosquito (“It’s small and annoying,” Stapleton said), emits a high-frequency pulsing sound that, he says, can be heard by most people younger than 20 and almost no one older than 30. The sound is designed to so irritate young people that after several minutes, they cannot stand it and go away.
