Fireworks displays are 1,000 years in the making
Modern technology perfects an ancient Chinese invention
As the legend goes, it all began with bamboo shoots and evil spirits. When fireworks originated in China, they weren’t much more than swaths of bamboo packed with black powder. Still, their blast was so ferocious that firecrackers were thought to dispel demons. Now, 1,000 years later, throngs of visitors are expected to line the banks of the Charles River on Wednesday to see pyrotechnicians blast shells into the night, painting the Boston skyline with resplendent sparks.
