Eurodoughnuts

There is something deliciously symbolic about the fact that the middle of the Euro coins are falling out when put in the refrigerator. Does it mean that there’s a hole in the currency when the European economy cools?

(Quick little physics lesson–the center of the coin is of a different metal than the outer part, and it has a different coefficient of thermal expansion, so when the metal cools down, the center part shrinks more, and loses contact with the outer part. Too bad the coin designers didn’t consider this…)
