The first time you see the demo video, you wonder where the sleight is. I din't see anything unusual.
The second time you might notice, that the handling looks a little strange.
When you look again after reading the description you will say: This is never going to fool anybody! But it just did! With the Ackerman Addition it is even more convincing.
This is a daring move. But the explanation and the fotos are very clear and easy to follow. The videos give you a clear picture of the timing and flow. It will take some work to make it look smooth and natural, but it should be within reach of anybody.
