The juggling pattern where every other throw goes over the top; i.e. one hand throws over, and one hand throws under. Usually discovered by accident just after learning Tennis, and just before learning the Reverse Cascade.

The full Three Ball Shower is a lot harder than the half shower; instead of throwing the ball inside, you pass it from one hand to another. Of course, this means that you need to have both hands free, and so you will have to throw the balls higher and faster than a cascade-type pattern.

The four ball version of the half shower is a form of five three. Each five goes over the top, while the threes go under.
