Abstract
Abstract An elongated inflated baloon has its intermediate portion passing through and secured in an opening in the wall of a hollow body so that an inner end portion of the baloon is disposed inside the body and its outer end portion extends outwardly, while gas communication between the inner and outer portions is maintained through the intermediate portion of the inflated baloon. While the outer end portion is held by hand of a user, the baloon is introverted by finger pressure directed longitudinally inwardly against its outer end, thus increasing gas pressure inside the baloon and providing reaction force for its propulsion along with the body when the baloon is released.
