Many years ago when I was a wee lad just getting into magic one of the first sleight-of-hand tricks I taught myself was the Multiplying Billiard Balls. Given the size of my hands and the cheap, smooth-finished balls I was using, it was a difficult task, but I kept practicing and eventually I could control them all in the standard grip seen at left. Little did I know that this forgotten skill would find practical application in the drinking of whiskey:
The only difference is that in the Multiplying Billiard Balls the objects appear one after the other, while in the Disappearing Shots of Whiskey they vanish in rapid succession. This is usually followed by my most famous trick, the legendary Drunk Magician Fails Spectacularly to Find Your Selected Card.
