A bungee jump is an adventurous, adrenaline kicking activity in which the person is attached to a rubber, very dynamic rope (with an ankle harness) and jumps in a verticular way. After few seconds of free fall, the rope will reach maximum tension and pull the jumper back up (rebounce) and this for two or three times. Once the rebounces are over, the jumper is hoisted back up to the platform with a winch system.
