The loading mechanism of the spud gun
s I had as a kid were ingeneous. The nozzle
at the business end
of the gun's barrel was poked into the tuber
to load a plug o' spud
the size of a Tic Tac
Compressed air would propel this plug into the ear of one's victim, or, if the attacker was more than a pace away from said victim, the plug would merely slam into the victim's cheek or eyebrow.
Or so I was told by someone who was there.
