Cannonball and Wahini

These closed tubes also scare you at first, because climbing a slide from this height is already brave. But here you can not see outside and with 120 meters the slides are quite long. You're getting faster and faster, pressed against the walls as you chase around the curves. At the end you shoot like a cannonball out of the closed tube into the run-out area.
