Last night I was cleaning my Foghorn trap gun and didn't pay attention to the large, full glass bottle of Hoppe's #9 on the workbench. It fell on its side from a height of 32 inches onto a concrete floor and did not break! I couldn't believe it! I was so dumbfounded that about half of the bottle came out before I was able to pick it up! Made the floor slippery as hell to walk on too.
