New Zealanders know how to make their own fun. They’ve taken to rolling down hills inside giant plastic balls called zorbs. Most contain straps to hold the rider in place; if you’re insane you can forgo the straps and fill the ball with water, creating a self-contained water chute.

The first U.S. facility opens this year in Tennessee. Brace yourself.
