The polarity markings Andy Gombos was referring to are printed on the
LEGO-compatible package itself. The LEGO "capacitor" is in fact an
electrolytic cap with plenty of support circuitry, and I assure you
there is no danger of blowing up the actual cap if the input polarity is
accidentally inverted at the package's inputs. I could just see it on
CNN: "Today, the Danish toy maker LEGO has recalled the LEGO Capacitor,
a member of their educational Dacta product line, after a series of
fatal capacitor-related explosions in elementary schools throughout the
United States..."
