Some Americans say July 4 is a perfect time for fireworks because of the U.S. national anthem, The Star-Spangled Banner. The song has words like “and the rocket's red glare, the bombs bursting in air, gave proof through the night, that our flag was still there...” But this Monday was a rainy day in the U.S. capital, Washington, D.C. There were low clouds in the sky over the National Mall and the Capitol Building, the site of a major fireworks show. The clouds made it hard for crowds to see the fireworks. PBS produces a television show of musical performances and fireworks on the Fourth of July. But when the show had images of fireworks exploding against a clear, night sky, people were confused. Especially people who knew it was a cloudy, rainy night in Washington.
