The scent of music

You’ll soon be able to smell CDs, DVDs and CD-ROMs. The multinational
disc-pressing company Sonopress is to offer recording companies a
“scratch’n’sniff” service. Sniffadiscs will be ordinary discs with labels that
contain tiny capsules of perfume, some of which are ruptured when the surface is
scratched with, say, a fingernail. The disc smells for a few hours. When it is
scratched again in a different place, more scent escapes. Sonopress will offer
honeysuckle, rose, strawberry or mango, to suit a musical mood, or trap the
fragrance of new-mown hay, petrol or leather for the relevant musical or
game.
