A bungee trampoline is a mechanical amusement attraction which contains a support structure of 3 to 8 m in height or 10 to 26 feet, a pulley system to anchor and retract bungee cords, a trampoline the jumper will bounce on, a harness to attach the jumper to the cords and structure, and a winch—either electric or manual—to put tension on the bungee cords by pulling on them through the pulleys.
A bungee trampoline (also known as a bungy trampoline) is an attraction at many fairs, vacation resorts and several summer camps. There are many different designs of bungee trampolines, but most operate in the same fashion. The participant puts on a bungee trampoline harness and is then hooked to several bungee ropes. Those ropes are attached to poles or bars reaching an average of fifteen feet above the trampoline platform. As the participant jumps higher and higher the bungee ropes are moved up the poles allowing the participant to reach heights and do flips and other maneuvers that would otherwise be impossible on a regular trampoline.
