There's something about a fireworks show that thrills you.
The booming launch of a shell, a thooomph! that puts you on the edge of your seat, waiting.
Then the wait. You know, in general, what to expect - but what will it look like?
BOOM! The shell bursts, an eruption of light. Fast-burning fireflies fly, glow, and then fade - setting the stage for the next one.
It's the best part of the Fourth.
