Q. The host of a party I went to said to take home two nice glasses as souvenirs. So I did, nesting one in the other. Now they are stuck. How can I separate them without breaking them? I know it has something to do with heat expanding and cold contracting, but I don’t know how.
A. I don’t know either. Well, I do know, and that is why I put the formula in my list of useful information. Place the bottom glass in hot water, to just below the rim, and fill the top glass with ice cubes. Physics takes over: The bottom glass will expand and the top one will contract and the glasses shall be free.
