Hey,
I posted a topic about this trick a while ago, but the videos in that were pretty terrible, and the description quite confusing. Since then I have completely remade the effect, so the handling is far smoother and the effect much easier to perform.
The video can be found here:

The lighting in this video is far better, and the bottle is clear, which should make it easier for you to see the coin inside the bottle. Also, as I was asked this when I showed the video to a friend, the bottle does not have to be opened after the coin has penetrated it. It is only opened in the video to show that it cannot fit through the neck.
The coin itself can be borrowed and signed, if you wish, and the bottle can be examined before and after the trick. Also, the coin doesn't have to fit through the neck of the bottle, as shown in the video. However if it does, the spectator can remove it from the bottle.
It doesn't just have to be a coin that penetrates the bottle either. A borrowed ring could be used, or a selected card. Other borrowed items could also be used.
Another aspect of this trick that I like is the fact that it can be instantly repeated. For example, if you met a couple and wanted to perform this trick for them, you could borrow a coin from each of them and make each coin penetrate the bottle, one right after the other.
I hope you like the new video, I'm really pleased with the new handling

Lastly, thank you for taking the time to read through all of this and watch the video.
