   Magic Trick: Coin Through Bottom of Bottle
  This trick is driving me nuts. Does anyone know how it works?   
  There is a coin-sized hole in the bottom of the bottle.   ;  cant be that. thats too obvious.   ;  Generally speaking, it doesn't matter how bad a trick really is as long as it's performed well.  In all likelihood, the coin never goes into the bottle at all.  I would guess it just appears to be inside the bottle, but is really right underneath the bottle showing through.   ;  They use a trick coin. It is able to fold in the middle and snap back when released. The trick requires some slight of hand. You pretend to push a real coin into the bottom while secretly slipping the trick coin into the neck at the top. You pocket the real coin as the attention is shifted to the bottle, which can be examined by the audience.   ;  Alternatly, you can set up a bottle with the coin already stuck to the inside with a light adhesive. The coin is hidden by the plastic label until you tap the side, causing it to drop to the bottom of the bottle. As in the other version you pocket the coin you started with as the attention is diverted towards the new coin.   ;  Ah. Thats cool. I saw the trick advertised somewhere selling for around $15. It stated that you could use any bottle so the folding coin explanation makes sense. Thanks Liquid Darkness. Of course if anyone has an alternative explanation I'm still interested.
