When I was a kid we used to make colourful fires by inserting garden hose into a copper pipe that had holes drilled through it.

Now that I realize how bad it was for the environment I really don't recommend you do that.

There are all these chemicals that change the colour of fire:
Copper Chloride : blue
Borax : light green
Copper Sulfate: green
Lithium Chloride: pink or red
Potassium Nitrate: purple
Epsom Salt: White
Strontium Chloride: makes red flame in campfire.
Potassium Chloride: makes a deep purple flame in campfire.
Alum (thallium): a nice bright green flame in campfire. Used for pickling but can also buy cheap at drugstore
Calcium Chloride : nice blue flame - is sold commercially as the product ” Damp-Rid” to get rid of moisture.
Table Salt (sodium chloride)- make an orange flame.
Boric Acid - deep red flame. Buy at any pharmacy.
