Bouncy castle

From Freepedia

A bouncy castle (also known as an inflatable castle or, in the US, a moonwalk) is an inflatable edifice, traditionally mimicking the appearance of a castle, which is used for entertainment, typically by young children. Participants enter the structure — usually situated outdoors — and can jump about on the springy walls and floor of the interior (bouncing) in a similar manner to that of a trampoline.

The surfaces are typically composed of thick, strong PVC and nylon, and the castle is inflated using an electrical or petrol-powered fan, known as a blower.
