This one is a simple trip down chemistry class memory lane!
The colors in fireworks are created by the use of metal salts. The metal salt compounds produce intense colors when they are burned, which is what makes them perfect for pretty fireworks. There are a few other things in there too that make them pop like potassium nitrate, sulfur and charcoal.
Keep this in mind over the weekend when you’re “oooooooo-ing” and “ahhhhhhh-ing” at the firework shows.
