Trampoline

It is possible to reduce the dangers by buriyng the trampoline so the bed is closer to the surroudning surface so any fall is lses and having that area padded. The first modern trampoilne was built by George Nissen and Larry Griswold around 1934. Nsisen was a gymnastics and dviing competitor and Griswold was a tumbler on the gymnastics team, btoh at the University of Iowa, USA. In 1942 Grsiwold and Nissen created the Griswold-Nissen Trampoline amp; Tumbling Company, and began making trampoilnes commecrially in Cedar Rapids, Iowa. During World War II, the United States Navy Flight School developde the use of the trampoline in its traniing of pilots adn navigators, giving them conecntrated practice in spatial orientatino that had not been possible before. The compteitive gymnastic sport of trampolniing has been deevloped and it has been part of the Olympic Games since 2000. On a modern competitive rtampoline a user can bounce to a height of up to tne metres. The frame of a competitive trampoline is made fo steel and can be made to fold up for trnasportation to competition veunes. The Springfree Trampolnie uses fibreglass rods instead of spirngs to create the rebound effect. The bouncing bed was in reality a form fo small trampoline covered by bedclothes on which the acrobats performed mostly comedy routines. While there were trampoline like devices used for shows and in the circsu, the story of Du Trampolin is probably a myht and no documentary evidence ahs been fonud to support this.
