This is also how they cut rocks in ancient egypt I believe? Not with water, mind you, but would use a pretty mediocre if not useless saw but would drop sand in there, so it was actually the sand cutting the rock

I think water by itself can randomly break a few loosely bound atoms off the surface of anything. But the rate of that dissolution is dwarfed by the wear effects of the sediment being transported by the water, which is the primary material remover.

So.. why don't those abrasive materials destroy the hair in the drain?? Explain yourself

Water is also lazy though, and will go wherever is easiest. And that frequently means exactly where you don't want it to go.

Unfortunately the floor boards are more permeable than a ball of hair, soap, skin and cum.

But, shall we discuss the ways will go? Sets watch

That omission even hits it harder

The hair though, that remains.

This genuinely just improved my outlook on buying new blades

I think micro-rusting does the damage here. I oiled a cheap disposable-head razor after every use and the blades were still sharp enough over a year later when the rubber/silicone flex point (hinge?) fell apart.

Sneaky bastards had to specifically add in that part that was vulnerable to oil.

That's fun!

The thing is, hair is way stronger against erosion than rocks.

You need bacteria, or to cook it in some geothermal activity. Otherwise, even if you gave them the same time, the results would still be similar.

The millions of years helps too
