Hi! This is your official PenguinMagic reviewer, B_Magic.
I used to do this effect a lot
back at an old restaurant I worked for. It was a big hit back then. The trick is fun to do and can
definitely get people talking.
The reason for 3 star review is that although it's a cool
effect and gets people talking, it isn't necessarily a miracle-status effect. Also, I ended up
having to stop doing the effect because all the cards plastered all over the restaurant ceiling was
apparently a fire-hazard we found out, and had to be taken down immediately. After that, the trick
got retired.
It's fun, it's cool, and people will talk. Just be aware that it may end up
more like a puzzle than a miracle to your audiences.
