Chewing gum
A confection made by blending sweeteners and flavorings into an insoluble rubbery gum base, intended to be chewed rather than swallowed.
The first retail barcode scan was not on a fancy gadget, but on Wrigley's chewing gum. On June 26, 1974, at a Marsh supermarket in Troy, Ohio, a pack of gum became the first UPC purchase scanned at checkout.
