You can add beautiful colors to your campfire while demonstrating the predictability and awesome design of God’s world.
Colorful Fire Logs
Select a large log and bore several holes about 1 inch in diameter in the log. Pack each hole with sawdust that has been soaked in a solution of one of the following chemicals. You may combine several colors in one log, or have one log for each color. Either way you will have beautiful colored flames in your campfire. Most of the chemicals will be available at your local grocery store, hardware store or drug store.
Chemical Color
Calcium Chloride used to melt ice Orange
Sodium Chloride (Table Salt) Yellow
Potassium Nitrate (Salt Peter) Violet
Copper Sulfate (bluestone) Blue
used to treat disease in cattle feet
Cream of Tartar Violet
Boric Acid Antiseptic Eye Wash (Borox) Green
Fire Cubes
Separate the cups of an egg carton by ripping or cutting in between them. Stuff the individual cups with the sawdust soaked in one or more of the chemical solutions. Set the little cups among the kindling and watch for the various colors to appear.
