Specialized candles are on the market that when lit, play "Happy 
Birthday" much like the electronic birthday cards. How does this 
work? There's a metal strip (aluminium?) that runs through 
the candle from the wick to the base so we're sure it's triggered 
by heat transfer but want more information.
