Black Magic - Prohibition

Cap in Bottle 

The Effect 
Here's the deal:. You borrow a normal beer or soda bottle from someone-anybody-at a bar, restaurant, party, or whatever You grab a couple caps off the bar and give them to the participants to examine; one that will end up inside the bottle and one to cap the bottle with to keep the bottle secured. 

You hold the bottle in your hand, snap the cap on the bottom once, twice, and bang! It is inside. 

As simple as that! 

You immediately hand the bottle back to the person you were working with to be examined; you are totally and unequivocally clean Believe it It is that quick Lighting fast.... 

Prohibition can be done totally impromptu, completely surrounded, and it is totally visual Seriously, watch the demo and see if you can catch it;!. They sure will not They'll just sit there and look at you with their mouths wide open -totally "gob smacked" as the Scots say.
