A really BIG gun.

I also know enough about black powder and smokeless powder to know that I don’t know enough to mess with them.

Very wise words.

I like to say, the more you know, the more you know you don't know. I think you know way more than the rest of us do. I don't really know enough to know what you know you don't know.

Think I'll stick with cannons that have no projectiles.

the more you know, the more you know you don't know.

as my Dad would say:
- He who knows not and knows that he knows not is a child. Teach him.
- He who knows not and knows not that he knows not is a fool.
Forget him.
- He who knows and knows that he knows is a wise man.
Learn from him.

If you lined it with pipe, this would make a cool little potato cannon. We used to get away with using abs (not pcv), with a screw on breech plug and hairspray, fired off with a piezo bbq lighter ignition back in the days before the internet safety police would say it's a terrible idea. I'm sure it is, but none of us ever had any incidents, even with some very hot loads.
