In the minds of many Americans, fireworks are an integral, and very familiar, part of community-wide celebrations. At the stroke of midnight on January 1, 2000, spectacular fireworks displays were set off around the world. Many of us fondly recall as children being taken by our parents to local fireworks shows that started just after dusk on the Fourth of July—a much anticipated summer event. Sporting events, from regular season baseball games to the opening ceremonies of the Olympic Games, often employ fireworks displays as a way to excite the spectators.
