In this sport, you jump headfirst from a high structure into the depths. You are in free fall. This is delimited above the ground by a rubber rope. The elastic rope is attached to your body and to the jumping platform. The length of the elastic is adjusted to your body weight. The rope is elastic and therefore bounces you back up several times until it swings out. Jumps are usually made from bridges or towers. In some cases, cranes are erected specifically for jumping off
