What color firework is the hottest?
Color tells us about the temperature of a candle flame. The inner core of the candle flame is light blue, with a temperature of around 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red.
What is used to explode fireworks?
Gunpowder is what makes gunpowder explode. Potassium nitrate is the most important part of gunpowder. A fuse is used to light the gunpowder, which ignites to send the firework skyward. Once the firework is in the air, more gunpowder inside it causes it to explode with a BANG!
What are stars in fireworks?
Pyrotechnic stars are pellets of pyrotechnic composition which may contain metal powders, salts or other compounds that, when ignited, burn a certain color or make a certain spark effect. They are a part of all projectile-type fireworks. The most common is the aerial shell.
