San-Tran by Chris Michaels

Apocalypse by Harry Lorayne
Volume 4, Number 6 June 1981
Page 501 et seq.

Personal Comment: Apparently there is a tiny bit of controversy around this. Al Smith published a trick call Entrapment in the Linking Ring Parade in 1980. That is identical to the version above. Only difference being the blowing in the end. Honstly, I think that is what makes up the beauty of San-Tran. And there is more. Seems like years prior J.K. Hartman published an effect called "Caught in the Middle" that is just like that.
Now that we got that out of the way... The effect might be clear as day for magicians, but I tried it. It seems not to resonate with normal people. I showed it to a few guys and most of them had a hard time to understand the effect. So I would suggest using a duplicate card. That way the selection is seen to actually go into the Sandwich.

Difficulty: 2/5
