Hi. I'm Mike Patrick, and this is how to do the classic Cups And Balls Trick.
You have three balls and three cups. You place one of the balls onto the center cup, stack and then snap, and then one of the balls magically goes through the cups.
I can do it again. I place this ball on top. Give it a snap of the fingers and the ball goes right through. It happens every single time whether you want it to or not.
And that's the classic Cups And Balls Trick.
Now this is a very fancy set of cups, but you can do it with any cups. If you have coffee cups that you can get from Starbucks, you can do it with Starbucks cups and some napkins. That's probably the best way of doing it, because you can just do it in front of your friends, impromptu. It's the easiest method.
You need three balls. Actually more specifically, you need four balls. The fourth ball is secret. They never get to know about this. The fourth ball is put in the middle cup. So if you have three cups, you should have cup A, nothing, cup B, that's the ball inside, and then cup C goes on the bottom of this. If you hold the cups in your hand like this, they can see the mouth of this cup, and by grabbing the bottommost cup, you rotate it towards yourself and you put it down.
The second cup actually has a ball inside of it, so you don't want to do this, because they'll see the ball. What you do is, again, you rotate it towards yourself, and you do it quickly enough, not fast, but enough so the ball doesn't fall out before the cup hits the table. You place this down.
This is essentially what you're going to be doing over and over again. So what you do, is you place this ball on top, you stack them on top, snap your fingers and show that the ball has apparently went through the cup. You do the exact same thing. Re-stack the cups. Place them in a line. Now there are two balls under this cup. When you place this on top, snap, goes through, and then finally you do it one more time, and that makes all three balls go through.
And that is how you do the classic Cups And Balls Trick.
