Bungee jumping
It started as the coming-of-age ceremony in a small                          village on South Pentecost Island in Vanuatu. The young men jump from the top of a 30 meter high tree to demonstrate their courage as an adult. They tied jungle vines around their ankles so that they would not hit the ground.And from then it started to become a sport in which people take part and it was named bungee jumping .
