Teambuilding and adrenaline
A swing jump is a jump on a rigid climbing rope that is fixed in the middle between two pillars. The jumper jumps from side of the bridge in clasic harness. It is about five meters of free fall, then when the whole rope is fully tensed, the first and greatest swing comes. At about 90 kmph. Every other swing is smaller until you almost stop. Then all you have to do is to abseil in the water and swim on the shore.
(part of the instruction is a shortcut course "How to abseil", It's pretty easy and everyone can handle it)
