What would sodium chloride and copper chloride do mixed?

Sodium chloride makes such a bright yellow that it usually drowns out the other colors. Unless you had a LOT of copper chloride, you would get a yellow flame.

If you could find a website that goes into a little more detail about the chemicals that produce the rich colors, could you post it on this website please? Thank you so much! Love your work!

How do you get fireworks in the sky? :D

sutterkids wrote on Mon, 05/28/2012 - 17:12:

do you think you could put up a chart of which powders make each color?

rkrampf wrote on Mon, 05/28/2012 - 23:43:

Done! Thanks for the suggestion.

I like the effects of the strontium chloride the best. Too bad it's the one hardest to get.

I love the video but how do they get the sparklers to go off 10 seconds after?

How do they make the amazing designs in the air? And how do they make such funny noises?

The designs are done by placing the spheres of firework material in just the right pattern inside the shell. When it explodes, it throws them out in that pattern. The screaming sounds are produced by sending the hot gases from the rocket through a special whistle.

the firework colors in it are amazing!!!!!!!

brevard wrote on Wed, 03/09/2011 - 11:24:

what happens if you mix all the chemicals together will it explode bigger then regular or will it be a another color or be a HUGE mess

rkrampf wrote on Wed, 03/09/2011 - 12:26:

Great question. The chemicals that produce the colors do not make the explosion. Instead, they add color to the flames. Fireworks manufacturers experiment with different combinations, looking for better, brighter colors. Often the mix looks worse, but sometimes they get new or brighter shades. They guard their recipes carefully, and fireworks experts can tell which company made a firework by the shade of the reds, greens, and blues.
