I was going to post a pic today from a recent trip to Banff National Park in Canada, but that would be downright unpatriotic. Instead of Banff, here’s a pic I personally didn’t take:
Ever wonder how the heck sparklers work? They’re pretty different, after all. There’s no explosion, as with a firecracker. No extravagant bursts of color, as with fireworks. Just a long, controlled beautiful burn.

- an oxidizer
- a fuel
- iron, steel, aluminum, or other metal powder
- a combustible binder
Since I write science fiction, and even though I’m more interested in people than science, here’s a science site that explains how sparklers work.
