I have to tip my hat again to David Regal. I might as well just give him the goshdurn hat. He never runs out of great ideas or improvements to old ideas. Ever since I met him on Pesach 2001, I've been a huge fan.
I bought his Sudden Deck on a whim Saturday afternoon at the local hangout after inspecting the contents and the instructions (it was the only one!) and played with it while watching the war on Saturday night. I didn't really get too excited about it until on Sunday and Monday, when I had the time to practice it in front of a mirror. It took about 5 minutes to make it look reasonable, and another 15 minutes of memorizing the patter and fine tuning the routine to make the act of folding the box look 'weightless' until the very end. It is very convincing and fair looking.
Today I started performing it. Taking the prepared item out from between some magazines in a rack next to my sales counter. It looks so innocent and so unusual that the spectator has no clue as to what (much less how) something can possibly happen. One young person said he saw the deck come from my sleeve, but I casually reminded him that I'm wearing a short sleeved shirt. Nobody asked to see the box as I casually tossed it under the counter.
I can tell you that in every one of about 5 or 6 performances it killed, and is a wonderful way to bring a deck into the forefronts of my customer's minds. They usaually expect some kind of magic anyway, but at the start it seems so ridiculous that the shock at the end leaves them speachless. It really does look impossible, and you will laugh yourself silly when you look at yourself in the mirror performing it.
