Adam: When I checked into my Kimpton room in Minneapolis, they not only had been pre-warned that I love Twix (thanks, Will!) but they also had a bar puzzle for me! A penny in a saucer filled with water. A glass and a book of matches. The trick was to remove the penny without using anything other than my fingers, but they could NOT touch water. I was also not allowed to move the saucer at all.
I figured it out. Here’s my solution! (Dec. 3, 2013)
