If you think that being hit in the face with a super-spicy wasabi mist is necessarily a bad thing, think again. A team of researchers from Japan’s Shiga University of Medical Science has invented a smoke alarm designed to wake up the hard of hearing in case of fire by pumping the mist into the air.
