Just playing around with a gas mask. You never know when you’re in need of a gas mask. My personal experience with a gas mask was way back when, the time and date has eluded me, evaporated in the time space continuum, never too be seen again. It was in the Navy though and I had to rip the gas mask of inside a gas chamber filled with this horrible gas, and then see how long I managed too stay in there before “passing” out, while giving the captain my serial number, name and rank. When you couldn’t stand it anymore you had to get out and run while you still were choking from the gas. The gas was stuck too your face, and you could only run it off, not touch it.
