A credit card machine with a small air pump and a set of rotating chambers that fill with a small amount of glitter. Really, an air-powered glitter chain gun.
When you make a purchase and your credit card (or debit card, for those more thrifty-minded) is approved, glitter is fired into the air, and everyone nearby cheers.
