Teen repellent wins Ig Nobel honour

ANY adult who ever fantasised about a magical remote control to silence unruly teenagers can now buy an ingenious device that scatters them to the winds.

For little more than the price of an Eminem-style designer outfit, parents will soon be able to operate an electronic teenage repellent, invented by Howard Stapleton, an engineer from Wales.

His device, called the Mosquito, operates like a dog whistle and disperses gangs of loitering teenagers by emitting a piercing shriek only they can hear. It has won him an award from Harvard University.
