Japan has currently made a website that maps smells. The website describes diffrent smells and then pinpoints them on a world map. It can detect more than 160 smells around the world including the pleasant scent of "used socks in the summer" the website has currently 200 members who are called "smellists".
Would you become a "smellist" if the website was in english? What kind of smells would you want to find?
I don't think you actually smell whatever you search, thats impossible...or is it?....
The japanese are actually working on something that lets the people smell these smells from their own home, but as it is right now, all the website does is locate the smell for you.
Interesting that with this invention you can smell over 160 smells and a few have selected vanilla? Just walk into bath and body works and you get punched in the face with the smell of vanilla and flowers. I'm not sure if I could rely on this to be accurate. sorry japan.
