Bungee jumping (also spelt 'Bungy' jumping) is an activity that involves jumping from a tall structure while connected to a large elastic cord. The tall structure is usually a fixed object, such as a building, bridge or crane; but it is also possible to jump from a movable object, such as a hot-air-balloon or helicopter, that has the ability to hover above the ground. The thrill comes from the free-falling and the rebound. When the person jumps, the cord stretches and the jumper flies upwards again as the cord recoils, and continues to oscillate up and down until all the energy is dissipated. The word 'bungee' originates from West Country dialect of English language, meaning 'Anything thick and squat', as defined by James Jennings in his book 'Observations of Some of the Dialects in The West of England' published 1825. Around 1930, the name became used for a rubber eraser. The word bungy, as used by A J Hackett, is 'Kiwi slang for an Elastic Strap'.
