The first trampoline may have been invented by the Eskimos holding Walrus skin in order to toss a person into the air; certainly people throughout history have had the experience of being tossed into the air on a blanket, and everyone can easily recall as a child jumping up and down on top of a mattress and bed springs. The first official trampoline, though, was the product of George Nissen and Larry Griswold, who invented the contemporary trampoline in 1934, seventy-six years ago.
Today, in the 21st Century, different types of trampolines seem to be everywhere, including the water trampoline. This recent version of the trampoline consists of a large doughnut like rubber piece, inflated with air, allowing the trampoline to float above the surface of lakes and pools.
Water trampolines are designed to float above the water line, and therefore there is little to no risk that it will become full of water; to put a water trampoline into a lake or pool, first lay out the tube on the ground and inflate it with air using a shop vac. Apply a UV protectant spray to the seal. Next, assemble the trampoline frame and attach springs to the jumping surface; after that, simply place the frame on the tube and fasten down the straps. Attach safety padding over the springs, then add a ladder and anchor (to hold it steady), then launch into the lake or pool.
To pull out the water trampoline, simply raise the anchor and pull or push the inflated tube back to the shore or lift it from the pool. If there’s any water aboard, tipping the tube should allow it to drain. Once on land, the safety pads and frame may be removed and the tubing deflated, reversing shop vac or air pump. You’re now ready to store the trampoline for the next outing.
