Unfortunately it doesn't make money appearing from nothing, but as some of you already know the trick is in the way to introduce banknotes in that.
I'm sure that girls could be very attracted by your magic trick and they surely want to play with your (full of money) wallet! ;-)
Step 1: The project
I drew a simple 3D schematic to show you the way to connect the ribbons which keep the money. Notice that although in the 3D and in the animation you see a space between the two plates, in reality the ribbons are very tense and they keep the plates adjacent.
Here a 3D model ready to explore with Sketchup preview.
