What do you do when you’re unable to hear a fire alarm when sleeping? Get one to spray you with wasabi.

Japanese people invent the best stuff. This fire alarm is for the deaf or hard of hearing. It more or less works exactly like a traditional fire alarm, except that it sprays wasabi up to 50 feet away (which is about 30 more feet than the average Japanese home needs). It’s now on sale for $560.

Here is something even more interesting about Japan. Whereas homes will always have a natural gas detector (because most homes use gas for cooking) I’ve never in five years seen a smoke detector. In fact from my very accurate study of asking random Japanese I work with about smoke detectors I can’t for the life of me find anyone who has one in their home. Awesome.
