The Mendoza Cups and Balls Routine (plus Sequel) (John F. Mendoza)
There are many points in favour of this routine.
First it does away with any vanishes that occur by placing the ball from one hand to the other.
Secondly, the antics of the balls are genuinely surprising and unexpected. There are no preliminaries to suggest to the spectator what the next effect might be.
The big loads take place separately and throughout the routine. They are not all loaded at the end of the routine. It has a logical theme to account for the loading in that, you make the spectatot think that you are trying to make it easier for him to follow by using less cups and less balls each time (you begin with three cups, cut down to two and end up using only one).
Thirdly the routine is easy to perform.
Finally the sleights are kept to a minimum and the subtlety of the cups and balls and chop cup combination set is employed.
