Bungee jumping officially began in 1979, but men on Pentecost Island in the South Pacific have practiced nagol, or land diving, for centuries. In a ritual full of symbolism and spirituality, men dive from a wooden tower up to 100 feet high with nothing but vines attached to their ankles.
On a recent voyage aboard the National Geographic Orion, the ship's expedition team helped a jumper attach a wearable camera to his chest, capturing a thrilling view of this ancient tradition.
