PBS Nova - Fireworks


Fireworks are danger held, like a sparkler, at arm’s length:
close enough to be beautiful, powerful, and alluring, yet far
enough away to be safe. This explosive NOVA presents the
colorful history of pyrotechnics and reveals the chemical
secrets that put the bang in the rocket and the fizz in the
Roman candle. The show introduces a gallery of firework
creators and pyromaniacs, and reveals how hi-tech firing
systems are transforming public displays into a dazzling,
split-second science.
