VERY TRUE!!Interesting video... but these guys are going to end up hurting someone. They have no idea of the pressures involved. With the 2-lb powder charge there were flames emerging from the BREECH of the canon. People and vehicles were within "striking distance" if the pipe cannon had exploded.

The guy i know tried to use a hydrogen bottle but they are so thick the ball wouldnt fitThink I remember reading about those that made bowling ball cannons/mortars and they used a different "bottle" to make them as they had a thicker wall. An "H" bottle? Can't remember what it was call as its been too long. They would toss a bowling ball about 600 yards. I think the max. charge allowed was 1/4 pound of cannon grade black powder
Still better than playing video games all day ….. and we survived ….. makes you wonder which generation had the better timeWe used to make what was probably more technically a mortar than a canon back in shop class in high school. They were made out of black pipe with a cap welded on one end and legs of whatever other steel scraps we could find. These were used to "launch" golf balls or super balls with an M-80 for the propellant. A few years older another attempt at self-destruction we were making tennis ball canons. These were made from steel beer cans and duct tape. Five cans were usually used for the main tube with both ends cut out. The sixth can was left intact (these were all straight wall pull tab cans by the way) with a hole poked the bottom of the sixth can. they were all taped together end to end with the pull tab hole of the sixth can towards the "bore" of the canon. A tennis ball would fit snugly into the cans as the projectile and was pushed to the bottom of the tube. The hole poked in the bottom of the sixth can was used to accept the propellant, lighter fluid. A generous squirt was put in the flash hole then the whole thing was swung in a circle to volatilize the propellant and then a flame was put to the flash hole and we had a tennis ball bazooka of sorts. A couple of phrases come to mind after remembering and recounting these stories. "It's a wonder any boy lives beyond the age of 21". The other, "the good LORD looks after drunks, fools and children", sometimes we qualified an all of these items.
We did the same, but got the idea to go around the lake in boats trying to shoot each other pirate style!

Did you and I live parallel lives? (Iron City Beer cans were the prefered item back when they were steel with a seam.) I recall watching the "owner" fire it from the ground like a morter. I had to try it (several times) as a bazooka.We used to make what was probably more technically a mortar than a canon back in shop class in high school.
