At The Museum of Useful Things in Harvard Square, the answer is definitely, "yes!" They will seal "anything that will fit" in a 16-ounce tin (probably aluminum, but you know what I mean) can for $4, using a wonderfully old and weird hand-cranked machine. How cool is that? They'll even can things that you bring in from outside the MUT. It might not be the most environmentally responsible form of packaging, but any gift wrapping that looks cool and makes the recipient work to get their present is a good thing in my book. Plus, we get to laugh at that old gag about Prince Albert in a can all over again.
