Often, as you watch a fireworks display, you will see a large burst that starts as one color, and then the entire burst changes to a different color. How do they do that?
Fireworks play a role in many holidays and celebrations. Have you ever wondered how they get the different colors into the fireworks? If you want yellow fire, do you add yellow paint to the mixture? No, that would not work. Instead, you need something that will burn with a yellow flame. Yellow flames are fairly common, but what about green flames or purple flames?
Have you ever wondered why a candle flame is yellow? And if you look carefully, you will see that the very bottom of the flame is blue! Why would that part of the flame be a different color? The best way to find out is to do some careful experimentation.
WARNING!
This experiment uses fire. Be very careful and safe.
This week's experiment is the result of a fire at my parents' house. No one was hurt, but it did cause quite a bit of damage. In case you ever have a fire, you should regularly check your smoke detectors. In testing them, we will also learn some about how they work.
I have been doing shows on the Science of Fire, so I thought we would do a fire related experiment.
As with all experiments that use fire, BE CAREFUL AND SAFE. Follow proper safety procedures and think about things before you try them. You should also have another adult with you, just in case you have an accident. That way, you have someone else to blame.
For our experiment, we are going to take a look at smoke. What is smoke made of? To find out, you will need:
