Introduction: Bubbling Fire.
This was something I came up with last night. Propane from a camp stove can is injected into the water inside of a bean can. Copper tubing 1/4 inch is bent over onto its self to close one end and a small hole is drilled into it. A hole the size of the copper tube is made into the can with a screwdriver. To make it watertight I used hot glue. Propane is feed to the can through a modified torch and aquarium air tubing.
This is fairly safe but it is still dangerous use common sense around fire.
Video is a little hard to hear. Also I do not have any video editing software. I used the cheap one that is built into the camera which at least let me merge 3 videos.
