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...)

I really doubt that the designers were entirely unaware of this. Several other coins, most notably (to me) the Canadian two dollar coin, have been discovered to do the exact same thing in the past.

Of course, if the Eurocrats knew the middles were going to fall out but went ahead and designed them that way anyway, it makes the whole thing even more deliciously symbolic. No wonder they were so afraid of the brutal Afghan winter!
