A Book of Extinct and Impossible Smells: “Robert Blackson is a trailblazer in the nascent field of conceptual scent art. He recently curated an exhibition at the Reg Vardy Gallery in Sunderland, England, that took viewers through fourteen significant points in time and space using only the olfactory sense.

…Blackson tasked perfumers, chemists, botanists and even a NASA scientist to engineer smells that most humans might never experience. Scents created include everything from long extinct plants to the fragrance immediately following an atomic bomb explosion. They even recreated the smell of the surface of the Sun, which scientists approximated by using the scents of seven earth metals heated to their melting point.

If There Ever Was is the companion book to the art exhibit. It features paper inserts that correspond to the exhibit smells, all manifested through scratch-and-sniff technology. That way, you can smell the putrid odor of Russian gym socks on the Mir space station without having to leave the comfort of your home (Cool Hunting)
