Thank you for that article. Once I get home from my deployment, one of these will be built on our AZ property as an intellectual exercise. My five children will get a hoot from it.
It brings a misty eyed tear to recall there was a time when, not only were Americans familiar with the name ‘Archimedes’, but were thought competent enough to handle hot things without warning labels and build cannons.
Those, my friends, were the days!
It ain't "harmless" if you put somebody's eye out with that thing!
Wonder how well it would work with plastic sabots & a load of BBs?
Hmmmm...a 6' length of 2" pipe....
