Everybody loves fireworks- but why? Behind the dazzling displays and fiery explosions is a colorful past as well as a complex and secretive science that goes back over 1000 years.

Join NOVA and travel to Italy, England, and Pennsylvania to discover the chemical secrets that put the bang in the rocket and the fizz in the Roman candle. Meet the Zambelli family, the "First family of fireworks," and see the spectacular results of secrets passed down through generations. Watch master pyrotechnicians show how intricate fireworks displays are created. Discover how elaborate computer controls turn a celebration at Pittsburghs Three Rivers Stadium into amazing split-second science. And enjoy some of the worlds most astounding public fireworks displays, including the record-setting millennial celebration at the Eiffel Tower.This program includes material that may not be appropriate for younger viewers.
