How do scratch and sniff stickers work?
It may smell like a banana. But you won’t find one under that sticker on your notebook.
A scratch and sniff sticker is packed with tiny capsules that hold scent oils. When you scratch it, you break open the capsules — and out comes the scent. Scratch and sniff stickers wear out after you break open all the scent capsules.
Perfume makers like using scratch and sniff magazine ads. The perfume is released from the capsules when you tear off a piece of paper glued on top of them. But not everyone loves reading a “smelly” magazine.
Scratch and sniffs are used in other ways. One opera director gave out scratch and sniff cards at a performance. The audience scratched several parts of the card to go along with the music and action. The cards had smells of oranges, perfumes and even rotten meat. You might say the show really stunk! – Anderson Herald Bulletin (Anderson, Indiana) – March 19, 1993
