Ignite the lab-made sparklers containing different mixtures of metal chlorates or nitrates and metals.
Sparkler burns brightly with various colors.
Sparklers are formed from a variety of different mixtures of metal chlorates or nitrates and metals such as aluminum, iron, and magnesium. Different metals produce different colors of flame. These gases provide the force that ejects the bits of powdered metals into the air, where they continue to oxidize and give off heat and light.
