It's nice, but I wish he did a couple things:
1. Include the gimmick. You can make this, but
you are going to need something you probably don't have.
2. He didn't teach how to get into
this. The video makes it look like you place the folded bill behind the card and then it instantly
flips into the card. Not so much. You have to set the gimmick and hold it in place.
Given he
didn't teach how to get into it in front of your audience, that leaves you with the constraint of
already having it set up.
It is a great idea, but it needs work.
