How far does the projectile go?
- cwkoss 5y agoI'd be very impressed if they were able to find any of the projectiles after firing

A friend's father used to build and test rockets using this principle, though he'd smear the outside of the rocket casing. During the Cold War. Up north. That earned the family a visit from an air force colonel one day, apparently after pilots had put together the sighting of high contrails, orange snow smears, and the lone figure seen trudging toward the smear.
- cwkoss 5y agoAh, that's a good trick. I bet if he greased a dozen ballbearings in snow, could probably find at least a few. I'd imagine these projectiles are going thousands of feet, would still be tough to find them all.
- jacquesm 5y agoDepends very much on the launch angle, anywhere from a few hundred meters to well over a kilometer. You can play around with this: https://www.omnicalculator.com/physics/range-projectile-motion https://www.omnicalculator.com/physics/range-projectile-moti... Note that it does not take projectile shape (and so drag) into account and that's the largest factor.
