蹦极也叫机索跳，广州人称为“笨猪针”或“笨猪跳”。高空弹跳蹦极起源于新西兰，是毛利族人的成人仪式，现已发展成为风靡世界广受青年喜爱的极限运动，是一项非常刺激的户外休闲活动。
Bungee jumping is also called the machine rope jump, Guangzhou is called "stupid pig needle" or "dumb pig jump". Bungee jumping is originated from New Zealand, and is an adult ceremony of Maori people. It has become the most extreme sport popular in the world, which is a very exciting outdoor leisure activity.
跳跃者站在约40米以上(相当于10层楼)高度的桥梁、塔顶、高楼、吊车甚至热气球上，把一端固定的一根长长的橡皮条绑在踝关节处然后两臂伸开，双腿并拢，头朝下跳下去。绑在跳跃者踝部的橡皮条很长，足以使跳跃者在空中享受几秒钟的“自由落体”。
A jumper stands on a bridge above 40 meters above the height of 10 stories, on the top of a tower, in a tall building, in a crane or even in a hot air balloon, and ties a long rubber strip at one end to the ankle joint, then arms out, legs up and down. The rubber strip tied to the jumper's ankle is long enough to allow the jumper to enjoy a few seconds of "free fall" in the air.
当人体落到离地面一定距离时，橡皮绳被拉开、绷紧、阻止人体继续下落，当到达最低点时橡皮再次弹起，人被拉起，随后，又落下，这样反复多次直到橡皮绳的弹性消失为止，这就是蹦极的全过程。
When the body falls to a certain distance from the ground, the elastic rope is pulled taut to prevent the body continued to fall, when reaching the lowest point, the rubber up again, people were pulling up, then, and fell, so repeatedly until the elasticity of the rubber rope disappear so far, this is the whole process of bungee jumping.
