This effect uses an old method but with new handling. I was familiar with the original method so I
didn't need any instruction on how to assemble the gimmick.
I was a little disappointed
when I saw that I already knew the method, but the new handling, and some extra preparation and tips
made it worth the purchase.
This video also gave me some ideas for how to use this with
mentalism.
It's a beautiful effect and I don't understand why people don't like it.
