I went to auto shop class tonight and the instructor pulls out an oxy-acetylene mortar that they had made.
He's a gun guy.
So he has these three projectiles made out of clear acrylic rod.
They are drilled out hollow and have a plug, creating a cavity inside.
He takes a light stick, activates it and then pours some in each projectile.
We got two rounds fired off from the auto shop parking area into the football field before the LAPD chopper started circling the neighborhood looking for the source of all the gunshot calls...
