What you get:

A tutorial showing you how to make this effect.

There is no talking, you simply watch them make one and follow along. The only sound is background music.

I found it slightly difficult to follow through the middle of the video because what's being done and where things are are difficult to see in the video.

So I just kind of partially guessed for some of it and managed to make the gimmick after a few hours of arts and crafts.

I made mines very tight and I'm not really sure if it's meant to be or not. Can it be looser? I dunno.

Overall, this feels clunky and rigid in my hands. Maybe because I made it too tight.

After getting all the way through the end of making this, I found out that U.S. dollars are too big. I suppose I could trim my dollars.

I think this might have some potential, because the gimmick only needs to be made once, but the tutorial is lacking any extra details.
