Reminds me of Army boot camp when we learned how well gas masks worked.
After they helped us ensure the mask fit, we were led into the "gas chamber", a small building full of concentrated CS gas which is a riot control agent. No problem breathing while waiting your turn. Then comes time to remove it. HOLY MOTHER OF... the mask worked extremely well while it was on!
I immediately bent over at the waist, snot reached from my nose all the way to the floor!! One by one, we were asked to say our name and social...then, we had to remember to put our helmet back on before being allowed to leave. Fun times!!
