A tub of popcorn

A large tub holds roughly one hundred seventy cubic inches by volume and, by weight, remarkably little: set on a kitchen scale, the same tub nets out near eight ounces of popped kernel and two of butter-flavored topping, the remainder being structural air, the same substance that makes popcorn what it is. Eleven tubs weighed across eleven venues hold the ratio stable enough to trust: this is a food sold by displacement, filled to a silhouette rather than a weight, and the flared shape itself, wider at the mouth than the base, exists to make that silhouette read as generous from across a concession counter. Kernels near the bottom arrive unpopped or scorched with some regularity, a tax paid for buying in bulk rather than by the handful; kernels near the top are the palest and driest, having spent the least time near heat, and are the ones passed hand to hand in the dark before anyone checks the level underneath. The striped paperboard construction, waxed against grease, folds flat for storage and holds its flare only once popcorn gives it a reason to. Butter-flavored topping pools at the bottom in a way no amount of shaking prevents; the last handful is reliably wetter than the first. Refills are priced per tub rather than per ounce, a policy the tub's own geometry quietly supports, whatever is left inside it.
