This effect always works and now it will be easier for you to do it than ever.

 It shows a large letter showing that it is a three, and on the other side it is a six.

But mysteriously when you turn the letter it is now one, and on the other side a four.  

Show that the effect is actually an optical illusion, since what you actually do is cover with your hands the hole or the point, making it look like a six or a four depends on where you plug.  

Once taught the secret, he says that there are many ways to do magic, but that you like it more than people see reality and now you show the letter with the three points on one side, and with the six points on the other side.

  This is already puzzling, but even more so when you finally turn the letter and on one side there is only one point and on the other there are eight.  

The effect is manufactured so that you do not have to worry about anything, as it is automatic.

In addition, it is the only one that allows you to be able to teach a one, a three, a four, a six and a eight, all of them with all the points.

Manufactured with the usual quality of Arsene Lupine
