You know like the kind that go on a window or bathroom mirror or on the wall or in the shower. They need the atmosphere pushing down on them to work, right?

I didn’t realize that the layer was thin enough to rub away with minimal friction. I’d learned about this years ago so I could be misremembering things, but the source I read made it out as if it wasn’t a major concern with space exploration because it took substantial effort to cold weld things that had been exposed to air.
Actually, it’s believed that some of the failures in early satellites was due to cold welding.
