Fire alarms are very useful in order to gain a few crucial seconds to escape in the event of a fire. But what about those who sleep listening to music or that often used headphones? For these people, who probably do not feel the sound of the alarm, there is a solution created by a group of Japanese students.
This is the Wasabi fire alarm, which not only sounds, but which also produces a source smell of wasabi (a condiment). You are able to hear the alarm or not, because the smell you find if there are problems.
The Group has created the Wasabi alarm has won the Nobel Prize in chemistry "for determine the ideal density of wasabi transported by air to awaken the people in the event of a fire or other emergency, and apply this knowledge to the Wasabi fire alarm".
