Sniff

Wouldn't it be great to be able to do a web search for smells?

Google, what does frankincense smell like? 

We can get a description -- see, for example, Facts About Frankincense and Myrrh -- but we can't actually smell them.

We can play a chosen song, or watch a favorite movie, over and over again. Bringing a smell to mind, however, is much more difficult.  We can catch a hint of an aroma, or try to recreate one with a candle or a cookie in the oven or a stick of incense, but it is never quite the same. If we close our eyes, though, we can almost imagine a scent. Sniff.
