If you’ve ever used a firearm, you know that the shell casing that ejects after the gun is fired is pretty damn hot. Definitely not something you’d want to catch with your bare hands when, say, a soldier is firing off a G36 assault rifle in front of you. I’m looking at you, German army instructor.
In the first 40 seconds of this video, the instructor is shown snatching several casings of hot brass out of the air and tossing them aside as if they were tiny acorns falling from a tree.
Well, that’s one way to stay warm.
