This one really gets your audience going!They love it when they think they know how you are doing the magic- and then they are surprised at the end!
You show a long card with four red dots on it, and one green square at the top.You announce that you are going to move the green square, but you tell them you have to do it in secret.You place the card behind your back (or behind a spectator's back, like Peter does with Dirk in the demo video).When you bring the card back into view, the green square is now ON THE BOTTOM!Of course, it is obvious that you have merely turned the card around while it was behind the back.
You then make the green square multiply- there are now TWO green squares!Behind the back again, and now there are five DIFFERENT COLOR dots!Of course, your audience will think that they "catch on" to what you are doing.They will loudly tell you to "turn the card around".When you do, the other side of the card has five different color SQUARES!
There are so many changes that you will be able to get a lot of time out of this one!
And that's all you need! Made of heavyweight coated cardstock.Measures about 10" long and 3.5" wide.
