I received an email the other day from the Zeiss Planetarium Bochum.  Staff recently celebrated the 60th anniversary of the Planetarium with a big party.  The institute’s lead artistic director baked a cake that was meant to look like something called a ‘meat hedgehog’.  It’s usually a German dish made of pork constructed to look like a hedgehog.  Because German’s love their compound words, ‘meat hedgehog’ is ‘mettigel’.  Naturally, this meant that the cake version needed a punny name.  Hence, I received the following picture from the Planetarium.

Congratulations to the Planetarium Bochum on 60 years.
