Well first of all, really? :(
It's clever but the description said "ordinary Objects". No,
you do need a few special objects.
Second, perform Live: Well can't do walk around or
parlor show unless you are able to setup. And doesn't look practical for a parlor show where people
move around unless, like he says in instructions, 'first trick in show'.
For 5 bucks, ok
worth it though. It's interesting to see how his mind thinks and the video is very instructive.
I think the description to the trick should be altered to indicate this requires easily found
objects at home and Penguin.
And that it is not good for walk around or impromptu. It really
very specialized for On-Line and Parlor.
