How do lubricants actually work?


From inserting certain objects outrageously easily, to slipping a persons trapped head out of a gate, lubricants dont shrink the inner object nor do they bend the outer vice to make room.

So how does lubricant make something enter/exit from a once impossible position?

In: Chemistry

Everything you see has little holes on it, like a golf ball. These holes grab each other as the objects touch. This slows down the object’s ability to move. This is called friction. Lubricants work by filling in all the little holes so that objects can slide smoothly past each other.

It seems you are talking about flesh. Lubricants work very differently inside engines and things like that. While bone are mostly rigid, flesh isn’t that securely attached. The old “head in the gate” trick is easier to get stuck, because pushing in the round part of the head makes a smooth surface to squeeze the flesh out of the way under the skin. Pulling back allows the gate to press two ridges of skin forward. The skin isn’t connected taught enough to keep the skin smooth. Lubricant, in this scenario, allows the skin to slide against the fence and the flesh squeezes under it just like it did to get the head through in the first place.
