skeletonbow: <snip> "tin foil" <snip>
I couldn't make out a word of this. I think it may be the aluminumitis in my ear.
Emob78: For one moment pretend that I don't know anything about chemistry, metallurgy, or physics, and just tell me what the hell is going on here.
At the risk of ruining the joke, skeletonbow was mocking both tinfoil hats and conspiracy theorists, by claiming that tinfoil is no longer made out of tin, but aluminum instead. (Which is true; lighter, cheaper aluminum replaced tin after WWII, but the name stuck. Kind of like how irons are no longer made out of actual iron, or cops ["coppers"] no longer wear copper badges.) He's pretending that there's a either a tin Illuminati of some sort, or that he's a victim of the Mandela effect.
Now you know, and knowing is half the battle.
