I Think this looks Like a pretty cool trick, but I have a small question. What Will happen in case the spectator isn't satisfied by the ratteling Sound, and decides to lift the cap unmotivated?

I know this could be a question of audience management, but i Think that the part of the demo video showing the trick up close seems a bit fishy at the moment he's placing the coin under the cap.

I'm not looking for any kind of exposure, and I believe that if it isn't possible to answer this question without doing so, I Will have my answer right there.

And if I'm already touching a sensitive area in means of exposure, Them mods Can just delete this topic.

But I ask because I'm interested.

All the Best.

They will instantly know the secret.

If you think it's gonna be an issue, then just rattle it yourself.

One example of audience management for this effect is to direct them to mimic your motions.

Thank you for your kind replies. I think I'm gonna buy it together with some other stuff I'm about to order, only when I've decided on the last few items.

Once again thanks.

Agreed. This is the must have trick of 2011.
