SMOKE ALARM:There is a smoke alarm for the deaf.

Invented by a team of Japanese scientists and engineers, this lifesaving device works by spraying vaporized wasabi into the air, which notifies deaf people of a fire – it will even wake them up if they’re sleeping!This invention won one of the IG Nobel Prizes in 2011, a spoof of the Nobel Prizes, for inventions that “first make people laugh, and then make them think”.
