My childhood memories of the Fourth conjure up cool evenings and hundreds of fireworks -- simulated bombs bursting in air in all their Francis Scott Key splendor. Every year this experience occurred with religious fervor, as my three brothers, mom, and dad, and even the family dog piled into the family sedan and the drove off to the nearest park to watch the fireworks.
In the early 1970s my family had a large boat-like convertible. With the top down, we’d park on a hill and overlook a larger region, taking in multiple fireworks displays. This spectacle was dazzling for young kids.
Every part of the early experience was fired by gasoline, powered by petroleum, or involved gunpowder and various chemicals. Quick flashes of light are created from the pop of gunpowder and the eye-burning bright flash from burning magnesium powder. Green colors are from powdered copper that is impregnated on paper that is wrapped into the firework. As the fuse burns the fire encounters each of the impregnated papers, and each gives off the various colors as they ignite, associated with the unique color of each element as it combusts. Cobalt for dark blue; copper for greens and red; and so on.
While the excitement of the display was initially captivating, as I grew older, watching the excitement experienced by others became equally or more entertaining. Parents usher children to focus and pay attention to the event, keeping them from spiraling into skirmishes and disinterest and distractions. The youngest children sit there like jello blobs with bobbing heads (a result of sleepiness, as they were out past bedtime), and wrenched necks from looking up, sometimes for hours, as every firework is launched.
Another summer favorite -- lightning bugs. And while I understand that watching lightning bugs is different than watching fireworks, in many ways it is the ultimate fireworks display. There before you are tens of thousands of illuminating insects dancing across the sky, some moving quickly horizontally, others flying upward 20 to 30 feet and then descending rapidly toward the ground.
