Inflatable Castles Structure Children's Houses Employees Designed Jumping

Inflatable castles, also known as "bounce houses" are becoming "increasingly" (more and more) popular in the United States. Today, it is common to see them at children's birthday parties, school "fairs" (festivals), "company picnics" (events where a company's employees and their families eat outdoors together) and similar events.

The first inflatable structure was designed in 1959. The "inventor" (a person who creates something) was trying to design an inflatable cover for "tennis courts" (the flat areas where tennis games are played). He saw that his employees were enjoying jumping on the covers, so he began to develop other types of inflatable structures. Since then, many other people and companies have created new designs, many with "enclosures" (something that goes around something else) that prevent children from jumping out of the structure and becoming injured.

Inflatable castles are usually "inflated" (filled up with air) with a "blower" (a powerful fan) that blows air into the structure "continuously" (without stopping), because some air is always escaping through the "seams" (where two pieces are sewn together) and small "punctures" (holes).

Now there are many "rental companies" that allow organizations and individuals to "rent" an inflatable castle for a short period of time, paying much less than the cost of buying a new inflatable castle. The inflatable castles have many different shapes. Some are designed to look like traditional castles. Others look like "ships" (large boats) or "haunted houses" (homes where there are scary ghosts). Still others have an educational purpose, such as an inflatable castle that looks like "internal organs" (body parts on the inside) and teaches about "anatomy" (the study of body structures).
