A Pringles Can

The hyperbolic paraboloid delivery system/Food & Drinks

The iconic Pringles can is a cardboard cylinder that stands about 30 cm tall with a 7.5 cm diameter. Each chip inside is a hyperbolic paraboloid, a saddle shape chosen so the chips stack perfectly and resist breakage. Once you pop, the fun geometrically does not stop.
