The lasers start out in their set pattern, and then go wild in an array of patterns pre set... but no nocker device is... without a flaw. So instead of a patriotic song, "She Blinded me with Science" blares through the neighborhood with the fireworks almost acting as percussion as the lasers make forms of famous American Scientists ! Oh well, a Brit song but the rest is all American. Ben Franklin's smile shines! Carl Sagan looks up to the stars! Jane Goodall is holding a primate's hand! And more.
