This 25 Inch Field Cannon makes a loud noise. Just prime it with some calcium carbide, water and trigger it with a spark from the flint mechanism and be rewarded with a flash and a boom. Or something. Check with the neighbours first, and the police second if you live near an airport, eh? $149.98.
Our 25 Inch Field Cannon is our loudest carbide cannon! This cannon features an automatic charger mechanism for rapid, multiple firing plus an automatic flint ignitor. Weighing 7 lbs, it operates on the same principle as a gas engine in an automobile–using gas, fresh air, and a spark. Powdered calcium carbide “ammo” is added to the water in the chamber of the cannon. The auto flint firing mechanism creates the spark to give perfect combustion.
I had this exact carbide cannon at age 5. Actually, my father played with it more than I. What’s of note is that I’m now 60 years of age. The design has not changed in over 50 years! I rather hope it has better material in the wheels than the “pot metal” used back then. One wheel broke in half. I guarantee it is LOUD.
