1. Thanks!

I was just wondering about this a few minutes ago while watching the local works. I can see them from my front room, porch, yard.

Hope everyone likes them.

3. Agree! there are now drones that can produce spectacular shows without all the

Pollution, fires, blindness and other injuries. To say nothing of the fear it creates for our animals. Thousands of Dogs and cats are so afraid, they run away, never to be seen by their owners again.

Let’s move forward and leave the fireworks behind!

5. No matter the color I was going for, I always put in the powdered iron, loved the sparkles.

Did I mention I was a teenager from hell?

6. I Used To Add A Little Sodium Tetraborate...

...to the smokeless powder we used in our pyro cans.
Boron creates a green color, while sodium creates bright yellow.
Given formula & relative mass, the colors are nearly equal and it creates a cool greenish yellow flame.
Did some additions with strontium nitrate to get deep red, too. But, it was way easier to get tetraborate. It's borax, and we could get it at the grocery store.
