"Of course, the secret lies in the fact that you have total control of whether
the spectator wins or loses so you can present the routine anyway you like"
I realy like it very much but 101 USD is a bit too expensive for my taste
Thank you Evan for the link but the one for $75 will be with shipping to Germany same price
And in the end more expensive with extra tax costs - so this is not realy a better deal for me
What i like about this trick, is that everything is always visible for the spectator, no hidings !
