I used the Bug-a-Salt gun yesterday to kill a fly on the counter. It was just lounging there, so I snuck off to get the gun, struggled to pump it, stood a yard back, aimed, and shot.
Hit the fly dead on. At first I thought he had been vaporized, because he vanished the instant after the bang, After some searching I found him standing on the kitchen table. He still had all his parts and wings. He saw me and walked slowly away. I didn't want to salt-blast my wood table, so I got the fly-swatter and tapped him. He wandered off in a different direction, shell shocked. I put him out of his misery.
He didn't seem to have any open wounds, so I guess maybe the gun gave him a salt overdose? Teeny-tiny heart attack? Regardless, it was very, very satisfying.
