Bounce houses, inflatable castles, moon bounces, inflatable slides and jumpy castles are all large-scale inflatable houses made for interactive entertainment. Commonly intended for children, bounces houses are made of PVC or other durable materials such as nylon or vinyl that when look like a house or castle when inflated. Rental companies deliver bounce houses to birthday parties, festivals, fairs and other events. The companies have industrial-grade blowers that fill the large structures with air to make them bounceable. A common size for a bounce house might be 15 feet by 15 feet by 13 feet. Bounce houses often have a flat, inflatable bottom pad and inflatable walls so that kids can jump and bounce without being hurt, along with a netting door and windows so that kids can see out and adults can see in. Bounce houses are suitable for both indoor or outdoor events, depending on the venue. For large events, rental companies often have a staff member who stays with the structure to monitor safety and keep it properly inflated. There are also wet/dry bounce houses with slides that you can hook up to a hose on hot summer days. A bounce house can be a fantastic addition to a party with kids, keeping them both entertained and contained.
