- Not to be confused with bungee jumping.
The reverse bungee (also known as catapult bungee or ejection seat) is a modern type of fairground ride that was invented by Troy Griffin in c. 1978.[1]
Skyscreamer
The ride consists of two telescopic gantry towers mounted on a platform, feeding two elastic ropes down to a two-person passenger car constructed from an open sphere of tubular steel. The passenger car is secured to the platform with an electro-magnetic latch as the elastic ropes are stretched. When the electromagnet is turned off, the passenger car is catapulted vertically with a g-force of 3–5, reaching an altitude of between 50 and 80 metres (180–260 ft).
The passenger sphere is free to rotate between the two ropes, giving the riders a chaotic and disorienting ride. After several bounces, the ropes are relaxed and the passengers are lowered back to the launch position.
Bungee Cord
The main Item used in this ride which happens to be the key element between all other items there, is bungee cord. The reason, of course, is obvious! Except maximum ejection altitude which mainly depends to towers' height, acceleration and speed of the ride depends on the bungee cord utilized there. Furthermore, safety (which beyond any doubt is what you think most when using this ride!) highly depends on this element. This is why best materials should be used [2] [3] [4] to build them and strict standards are applied for implementation and use [5] [6][7][8] [9]. However, that is not all! after implementation and using the ride one should keep it mind that you can do only a limited number of jumps with this bungee cord and it should be altered after a certain number of jumps regarding declaration of the company from which you purchased the bungee cord. It varies from company to company and may be about 350 jumps [10]. This need to replace bungee cord along with the cost of each bungee cord price (which varies between ~ 70-250$ per meter) may make this ride a little expensive for some users.
Safety and possible injury
In August 1998, Jérôme Charron died in a reverse bungee ride accident at the Ottawa Exhibition in Ottawa, Ontario, Canada when he was hurled 40 m into the air before plummeting to his death as his harness had detached. In February 2000, the firm responsible for the ride, Anderson Ventures, was fined $145,000 for this incident.
Ordinarily, the bungee cord is changed to adjust the body weight of different riders. The operator in Ottawa instead used a lead between the carabiner and the bungee cord for this purpose. Using a lead is faster than changing the cord, so more rides can be offered; however, using a lead is less safe than switching bungee cords. The problem occurs when the lead cord wraps around the carabiner, tightens and through friction undoes the twisting safety mechanism that keeps the carabiner locked. In this case, the operator was using dual carabiners. On the bounce back up, the lead cord tightened, causing both carabiners to open. This fact was discovered by the Ottawa Police who investigated the death.[11] A video of the incident depicts it.[citation needed]
Provincial inspectors had inspected the ride just 4 days before the incident and approved it, but did not see the lead because it was in a nearby box.
