This has potential to be a great effect.
If you truly believe this trick is worth it, you can:
You can keep this trick to yourself, perfect the method, and post up a street video in a couple of months after perfection.
Take into advice that as soon as you create a new effect, you may not want to tell people right away. I created a Card Halfway Through Window but when I told the forums here about it, I realized the several flaws my performance would have.
SO, what you want to do, is pefect your idea first. Have the method, have a script and performance for it, and perfect it on the streets. THEN show the forum members this video, rather than telling us your effect which could very well not be a great presentation, just something that sounds good on paper as an effect.
I hope I didn't come across rudely.
However, it does sound like an interesting effect and I would love to see a video of your trick after it has been perfected. Also, a good hint for a routine would be a coin through bottle, and then do a coin halfway through bottle.
