The "Button trick", as its generally known, is associated with Max Malini. It was a signature effect for him, a reputation maker, that broke the ice, opened doors and gained him many bookings.

Now you can get in on this good thing.
Item 501 will quickly become a regular part of your working repertoire. You'll use it impromptu, at cocktail parties, in your restaurant work, almost everywhere. If you don't order yours today, you'll kick yourself tomorrow when you see the reaction an audience gives someone else. Don't be left out. The applause you here could be your own.
