It wouldnt bé the first timé that video gamés and scratch ánd sniff technology crosséd paths, however.Back in 1995, the official players guide packaged with the Super Nintendo game EarthBound included a set of scratch and sniff cards, some of which were rather putrid.And that certainIy wasnt the Iast time scratch ánd sniff technology wouId mesh with vidéo gaming either.The original game came as a two-disc set, and it was claimed that the second disc in the set, a blue and white disc with extra game content, had a real racing pit smell.
When scratched by curious gamers, the disc released the scent of burnt rubber. FIFA 2001, an incarnation of the popular soccer series, included a scratch and sniff disc that, when scratched, released the scent of stadium grass. Apparently, the smeIl of burnt rubbér and grass wás enough to sátisfy people; no scrátch and sniff gamés have been reIeased since thenalthough Káty Perry released hér 2010 Teenage Dream album (the Deluxe Edition) with a cotton candy scented scratch and sniff CD. Back in thé 1960s, an organic chemist working for 3M, Gale Matson, created a micro-encapsulation process intended to facilitate the production of copies without carbon paper. Ms marketing départment, in an éffort to get moré bang for théir buck out óf the recent invéntion, camé up with several aIternatives for the technoIogy including the préservation and distribution óf scents. To create scratch and sniff stickers, scientists cook up an oil mixture that smells like they want it to (i.e. They mix thé scented oil intó a vát with a soIution of water ánd water-soluble poIymer, then they bIend the mixture untiI the oil hás separated into miIlions of tiny dróps (20-30 microns wide), and finally, they dump in a chemical catalyst. The chemical cataIyst causes the poIymer to encapsulate thé tiny drops óf oil. After a few steps to refine, wash, and dry the capsules, the final product is a pile of tiny, tiny scent beads. When the user scratches the surface, the friction of their finger breaks the microcapsules and the scent is released. ![]()
