Growing up, stepfather had a half gauge naval cannon. Little V-8 cans fit perfectly. 1 can of cement, 1 can motor oil, one can gasoline....and load.
First the gas hit the air an ignited...you feel the heat and a big white light. The oil made white billowing smoke rings & clouds that rolled across the back yard. Then the whistling of the concrete through the trees & leaves to complete the re-enactment....it was just too cool.
