What is "bowl-a-rama"

Bowl-A-Rama is a stage magic trick invented by Kevin James.

The magician holds up a pad, on which he draws a picture of a bowling ball, with the words "Bowling Ball" surrounding it. He then closes the pad, holds it in front of him, and a physical bowling ball appears to drop from the centre of the pad. The magician then re-opens the pad, revealing that the picture of the bowling ball has disappeared from the paper, although the words remain.
