Procter & Gamble is doling out tiny speakers that fit on the top of any Pringles canister. The speaker uses the empty canister to amplify sound when it’s attached to an iPod or other music device. According to Kristin Herrmann-Ratz, Pringles brand manager, the summer-long promotion is a way for the brand to help consumers make “good times even better.” “Pringles is about unexpected fun,” she says. The speakers are free by mail for consumers who purchase any four Super Stack flavors.
