Fireworks originated in China some 2,000 years ago, and legend has it that they were accidentally invented by a cook who mixed together charcoal, sulfur, and saltpeter -- all items commonly found in kitchens in those days. The mixture burned and when compressed in a bamboo tube, it exploded. There's no record of whether it was the cook's last day on the job.
