Is this a joke? It appeared on April Fools Day! Google Nose says that it can connect scent to search. If true, I think this has amazing aromatherapy applications. So let's say that you feel a little tired, why not search for the scent of citris via Google Nose, take a whiff and get a lift on the go?
Here is a short video on this amazing (?) capability. And check to see what scents can be used for which needs and emotive states in the Aromatherapy section of my blog.
