Adding air through the fill valve moves the piston forward, allowing air to leak into the reservoir. The air supply is then disconnected, and the trigger released causing the piston to move backward. This releases all the air in the reservoir into the barrel instantaneously, resulting in faster ping pong balls and potatoes.

The Coehorn Mortar
Baron Menno van Coehoorn was a Dutch military engineer who lived in the 17th century. A master of siege warfare, the good baron developed the high trajectory mortar that sort of bears his name.
Modern Home-Brewed Examples
The barrels come from www.blackpowder-cannons.com. They offer a variety of fascinating DIY gun projects, but their Coehorn tubes come in two flavors. The 1.75″ version shoots golf balls. The larger 2.625″ gun throws aluminum beverage cans. These two barrels will set you back $55 and $100, respectively.
The Build
Anyone even reasonably handy with tools can conjure the carriages. Power tools certainly make the project easier, but our Civil War forebears did just fine without them. Nondescript pine lumber renders fine service as raw material.
Ammunition
The smaller gun shoots golf balls. I don’t play the game myself, but a trip out to the local course for a meeting with the groundskeeper bought me all the practice balls I could ever use. These guys gather old balls up and sell them on the side for a little spending cash. $20 got me a bag full.
Feel the Power
So what is it really like to touch off one of these little monsters? The golf ball version will quite literally throw a golf ball out of sight. In fact, I’m not sure these things ever came down. I’ve yet to find one. The Coke can version is a freaking mule.
Practicalities
These two homebuilt Coehorn mortars have no practical applications beyond spicing up your golf game. You’ll not use them for home defense, and you’d be better off with a proper baseball bat if you spot zombies staggering up your little cul-de-sac. These nifty little cannons are range toys pure and simple.
Ruminations
Yours may be a truly epic gun collection already. You may have Patton’s ivory-handled revolvers and Han Solo’s original DL-44 blaster hanging on your living room wall. You might even own the very 1873 Colt Peacemaker than Moses himself had strapped to his hip as he led the Israelites out of Egypt and into the Promised Land.
