"Whiffle ball"!! A number of years ago, I was asked by the Watervliet Arsenal to demonstrate my breechblock falcon for a tape to be shown in the museum visitor's center. I was with General Solomon, the Commanding Officer of the Army Ordnance Corp and the incoming and outgoing colonels of the arsenal. I surmised that the safest place to discharge the cannon was at the nicely fenced-in manicured putting green of the commanding officer.
Did you know that a tennis ball sized styrofoam ball is made-up of a guhzillion pellets?
The green was blanketed.
I looked at the camera and said, "Guess I should have used a putter?".
They shop vac'd it after I left.
