Land diving is a ritual performed by the men of the southern part of Pentecost Island, Vanuatu. The precursor to modern bungee jumping, men jump off of wooden towers around 20 to 30 metres high, with two tree vines wrapped around the ankles without any safety equipment. This jump is traditionally a fertility-rite ceremony only for males, some as young as seven, although it is said to have been started by a woman who was annoyed with her husband. He followed her up a tower, where she tied vines around her ankles and jumped. Unfortunately for him, he forgot to tie the vines and fell to his death.
