Abstract: A display apparatus simulates a container of gaseous liquid. The display apparatus has a reservoir formed by closely spaced inner and outer walls, at least the outer wall being transparent or translucent and shaped to resemble the container. In use, a foamable liquid is held within the reservoir, and gas is introduced into the liquid at the bottom of the reservoir to thereby form bubbles which rise through the liquid and form a head of foam on the liquid. A foam regulating mechanism allows the gas from burst foam bubbles to escape from the reservoir, but returns the liquid component of burst foam bubbles to the reservoir. The display apparatus is suitable for simulating soda drinks, beer and other aerated beverages.
