This is a video of full-of-flair bartender Stephen Molloy demonstrating a shaker and lime slice magic trick reminiscent of the cup and ball magic tricks of old. Admittedly, the minute-long trick is pretty impressive, and ends with a surprise that, unfortunately, was not the drink I ordered five minutes ago. What the hell Stephen I came here for a quick beer, not a magic show.
Keep going for the trick.
Thanks to Shauna, who informed me she's just happy when she gets the right drink.
