My anvil is a 3" jeweler's anvil, wonder how far I could get that one to fly?
My favorite was an acetylene cannon; if you take a golf ball sized pipe, put on a cap with a hole drilled in it, and stuff a golf ball half way down it; you can clamp the whole thing in a vice, hold an unlit acetylene torch up to the hole, light the torch and stick it back on the hole. Da buggah’ll shoot dat golf ball ‘bout a half mile (almost a kilometer)!
Last I heard, they weren’t sanctioned by the PGA.
