Each village builds at least one tall wooden tower every April.
Villagers remove all the rocks near the tower. Then they cut vines to the right size.
They want their heads to barely touch the ground when they jump. But the vines can't be too long. They don't want their heads to get too close to the ground! The boys jump first. They jump from platforms that are 19–20 feet (6 meters) high. Men jump from higher platforms. As a man prepares to jump, his friends tie vines to his ankles. Then he raises his hands and gives a speech. The people below stop singing, dancing, and whistling. The performer crosses his arms over his chest. He leans forward until he falls off the tower. Sometimes the vines break. However, the slope and the soft soil help prevent bad accidents.
