Very fun little trick, can be presented a number of ways. If you're life is even remotely related
to psychology, medicine, art, etc. you can naturally present this. It can only really be done once
within a group of people - once someone has seen it, you can't perform it again even if they didn't
"do" it so its best 1:1. And one reveal is just so much better than the other, I find myself
praying for it. But, for what it is, its a lot of fun and the various presentations and methods
allow you to adapt the concept to other "make your own" tricks. Worth the buy.
Is the reveal you say is "so much better" the one shown on the demo? Because I think that's the weaker reveal. I was surprised (and pleased) when I got this that the above was the case. How many times, comrades, on an effect with MOs do you get shown the ideal one, and all or at least one of the others are dogs, right? I know he thinks the demo'd reveal is the best - he says he prefers it because it's more theatrical - but I think it's less emphatic.
