It was "before" I tasted it - I couldn't get near the glass. I was sweeping up a bit and the glass was on the bar and the glass started to wobble and the contents sloshed in the glass. I poked it with the broom stick handle and that's when the contents jumped out and ate the top of the broom stick handle.

I think it is a potion of some kind. Where did they get that recipe? It will scare the daylights out of you - I wonder what else it can do?
