The cheater's shower (side cascade, or navy shower) is a cascade where you throw each ball with your arm extended, while all catches happen with your arms close to your body. From the front, it's not much to see. But from the side, the cascade will take on the appearance of a shower pattern.

Tips/Hints: When you turn, use the hand opposite of the direction you're turning to give a nice high throw. The high throw gives you plenty of time to turn, catch, and continue with a normal cascade.
