OK, on America's Got Talent last night, one of the magicians, (Nathan Blick?), did a very clever trick. He's done variations of it in several appearances, but less concentrate on last night, because it was simple and I can't figure it out.
He comes onto the stage pulling a wagon - sort of an oversized Radio Flyer-type wagon, with a structure on it the size of a small telephone booth. The structure is made of clear plastic/vinyl, and made to look like an oversized Barbie package. He pulls up a small curtain which was straddling the structure at the bottom, leaves it there for a second, pulls it away, and reveals a woman (dressed as a Barbie figure, leading to a bit of comedy schtick thereafter).
The wagon appears much too small to conceal the woman in it's base. The structure has clear walls all the way around, and he does a 360 loop as he brings it on stage so you can see there's nothing unusual behind it. It's transparent so it appears there can be no false walls or anything. The wagon base is elevated from the floor so it appears impossible that the girl came up from the floor, and you can see over the top so it appears impossible she came down from above.
I had it Tivo'd and watched in slo-mo and saw nothing obvious...
So how'd he do it?
