A pnenominal break-through from Google! Being in a beta-stage a search by smell lets you find any object basing on its scent in a huge database with the help of a special mechanism. You can not only smell an object you search but also share this aroma with your friend! Hope it will be a pleasant one:)
Moreover, you will be provided with a detailed description of any scent present in the database. Take for example, campfire: charcoal, toasty smores, smoke...So, I am not going to spoil you all the story! You'd better see it:
By the way...Happy Fool's day!
Someone caught by Google tricks?:)
