Gasoline, again. This time, burned with water and air. The pot seen sits on a stove element set to max, and in the center of the pot suspended above it sits a small tuna can filled quarter-way with gas. The can had a "funneling" shroud around it to pull more steam into the burn. Before placing the gas in the steam the water must be boiling and gas lit. At first, it erupted into a two-foot scorcher, but no soot was seen. After the lighter stuff burned off it died down to a small bluish flame, all the while no smoke whatsoever.
