Well, if you extend a rubber band, after a while tension begins to build up and the rubber band wants to retract (return to its original shape), same principle with a bungee jump, the band is extended to it's limit and wants to return.
That is potential energy stored in the elastic bungee rope, which turns into kinetic as the rope contracts and the rider starts to rise again.
A stretched rubber band has elastic potential energy.
Yes, potential energy is an energy something has because of its position in a gravitation field. Thus the jumper standing on the bridge before the jump has gravitational potential energy. When the jumper jumps the gravitational potential energy is converted into kinetic energy (the energy something has because of it motion) an is also stored in the rubber band as elastic strain energy. When the energy stored in the rubber band exceeds the kinetic energy the jumper halts and bounces back and the energy in the rubber is re converted into potential energy. The jumper oscillates on the rubber rope until the energy loss due to friction and wind resistance uses up the potential energy present in the system at the start of the jump and the jumper hangs still from the rope.
The mass affects the stretch of a rubber band because heavier objects apply more force, causing the rubber band to stretch further due to the increased tension. The greater mass increases the gravitational pull on the rubber band, leading to more deformation and elongation.
Rubber bands, bungee cords, and elastic waistbands in clothing are examples of elastic materials. These materials can deform under stress and return to their original shape once the stress is removed due to their elastic properties.
You can affect the extention of a rubber band by putting weights on it. The more weights you put on a rubber band the higher the extention will be.

If you do it at a sanctioned jumping facility. With personnel that are trained. You have a better chance of being struck by lightening twice inside a rubber building. Safety rating is what you should be concerned about. The highest safety rated country in bungee is Japan, followed by Canada and I believe NZ. USA is somewhere in the top 10.
Because the first bungee jumps were done on giant versions of the common bungee cords that people use for everything from keeping an overstuffed trunk lid down, to attaching luggage to a luggage rack. They are called Bungee cords. The first jumps were done on large versions of those cords... 5/8" to-3/4" to- 1" inch diameter. Made primarily for the military for heavy duty applications such as attaching heavy equipment such as tanks to parachutes for equipment drops. So since the cords they did these first jumps from were called "bungee cords" they named the new activity "bungee jumping" Then about 8 yrs later after "bungee jumping" had caught on and had spread to the U.S. where the first commercial bungee jumping business had already taken off. Down under a New Zealander had decided to get in on the new craze and began trying to figure out a new system of cords to perform the same jumps. He found that you could buy the same latex rubber in bulk, that was the same as the rubber inside the "bungee" cords. It came in long continuous length ribbons. He found a way to wrap it around a spool on each end, round and round and then finally tying it off. The cord was then stretched out and bound with the same rubber in a dual helical binding to keep it from flying apart and the jumper getting caught up in the rubber during the rebound. These cords have different characteristics during the jump than the machine made "bungee" cords. Bungee cords are made with a machine called a braider. The rubber is stretched tight before going through the braider where the machine weaves a braided sheath around the stretched rubber.After the cord is finished the rubber inside stays stretched out tight so the jumps done on these can be made using a longer cord, resulting in a longer freefall. The cords designed in New Zealand are spongier and stretch longer, so a shorter cord has to be used. Since these cords are different from the usual bungee cords that had already existed he felt they should have a different spelling...hence the name and spelling...Bungy
With bungee cords and/or rubber bands.

salt has no affect on rubber
wind has no affect on rubber
12,306 deaths... Just what is your source for this?...Not to be rude but this figure is absolutely ridiculous! I have been involved in the bungee jumping industry since 1989. And I have been aware of just about every single death that has occurred. I say just about, because I do not claim to be omnipotent in every thing bungee, NO ONE is but i am absolutely positive that that figure of 12,306 is AT LEAST overinflated by 100%. that would mean that the actual number is closer to 123. Even that number is higher than the actual number. I have not kept a log of all of the deaths but i would say the real number is closer to 50, actually somewhere between 50 and 100. For someone to say that 12,306 people have died jumping is stupid and irresponsible. Bungee jumping can be incredibly dangerous when performed by the wrong people, people who are not expertly trained, irresponsible or just plain stupid lacking any common sense. ALL of the Fatalities have been caused by human error..ALL THEM!!! There have been instances when people have died or been seriously injured where to watch the incident happen, it would appear that it was because some part of the system usually the cord had broken or failed. But this has never been the case. Upon closer inspection by someone who is an expert in bungee jumping , All of these accidents have been cause by HUMAN ERROR. Bungee jumping is an inherently dangerous activity, after all you are jumping from a lethal height attached to nothing but a large rubber band! But when done in a manner that has been proven by hundreds of thousands of safe jumps. It is a very safe activity!!! ...........ElasticAddict............www.webstarts.com/bungeejump

by burning the rubber because it can affect our air
