Place one of the bottles from the back bar on the bar in front of customer.

Bet them that you can drink a shot from that bottle without opening the bottle.

Secret is just make sure bottle has and indentation in the bottom of bottle.
(Like a Champagne bottle)

Pour a shot in the indentation of the bottle and drink it and your WINNING.

But it has to be a liquor bottle. So before hand
you can check out your bottles and know which one to use.

That seems fun thanks!!!!

I love this one!

Very clever will have to try sometime. Though how many times do people actually take you up on this?

I'm guessing you can only do this once a night, lol
