The objective is to catch the ball in the cup.
No need to worry if you miss, as the ball is attached to a string that is attached to the cup!
Storage is as easy as catching a ball in a cup!
It's basically a large wooden cup with a handle to grab, attached to the handle is a string, and attached to the string... is a ball. The goal is to get the ball, in the cup.
