So here we have my second attempt at shooting the cannon. We are using a tank of gas with a torch tip that has been modified with a short length of copper tube as a pilot light. I also have a smallish back yard so I am only shooting 2 ounces from a short barrel for each shot, though at 60 lbs it will shoot up to a gallon of fuel. In this shot I used some copper chloride II to color the fire with green and blues. I purchased my copper chloride from skylighter.com because they have been around for years and I highly recommend them having worked with them for some time.
Here you can see the blues and greens in the fireball. This is very hard to capture with video or a camera, but the colors are very vivid!
Our first test shot of the fire cannon. For this shot we dissolved some Lithium Chloride in with our alcohol to produce a deep crimson red fireball.
Here we have a short how to for making our copper solution and test firing.
