Alice's Reflection

Today in block 1 of Aliens we did an experiment in the lab. We were using a bunsen burner flame and burnt 5-6 different chloride substances which were: Copper, Magnesium, Sodium, Lithium, Strontium and Potassium. When all of them were put under the blue flame they all turned the flame different colour depending on what substance you used on the flame.
Here are what colours they turned into:

Lithium chloride: Bright red fire, Copper chloride: Vibrant blue and green colour with some sparks in it as well.Strontium Chloride: Yellow in the middle and bright red on the outside.Magnesium Chloride: red with slightly red colour as well.Potassium Chloride: A red/magenta colour.

I believe that this was an actual representation of the colours in space. One of the best examples is that on the bunsen burner the yellow fire was actually colder than the blue flame which was way hotter than the yellow one. which is just like the stars. Stars that are very hot turn a vibrant blue colour and starts that are bright red are colder. Also, a few of the experiments were like that as well when you added certain substances which would turn some a bright red or blue and I believe that the blue flame
