Paint.
Orange to be precise.
When I was a kid, a friend of mine hosted a birthday party on a paintball range. We played for I don’t know how long, large group of us, was really fun.
One thing the instructors told us, keep your mouth shut.
You see, we wore face masks, however for us to breathe of course there’s a grill where you mouth goes.
Needless to say, I got shot right on that mouth grill, and naturally due to the shock of it I opened my mouth…
The paintball burst on the grill, and I had the whole volume of paint launched deep into my throat.
It was so… ungodly… salty. For the rest of the day all I could taste was salt (the blow occured around early afternoon). And that’s coming from someone who also on another unrelated occassion ended up with a deep mouthful of sea water.
Damn right it’s a national security concern, let the US keep it’s spyware to itself.
