"The Best Guests Come Bearing Gifts" . . . Wasabi Fire Alarm

by SUSANNAH LONG · April 28, 2010

Genius idea: Fire alarm sprays wasabi scent to alert you.

Good for deaf buddies. Especially if they smoke. And it's effective!

Test subjects woke up within two and a half mins. Danger averted.

Who knew wasabi was such a spicy savior? Hurray for strong smells!

Cost: Five hundred and sixty dollars. Worth the price. The Japanese win.
