did you know soap doesn’t really clean your hands it just makes the water molecules smaller so the water can go into smaller crevices in your skin isn’t that the weirdest shit you’ve read today
Not true. Water molecules are of a fixed size.
Soap cleans your hands by making things that don’t normally dissolve (like oils) able to dissolve
Molecules have a property known as polarity, and basically, polar stuff dissolves in polar stuff. Non-polar stuff dissolves in non-polar stuff but non-polar and polar won’t mix because polar molecules are snobs who gather together and ignore non-polar molecules. Water is very polar, oils and fats are largely non-polar. This is why they separate into layers.
Soaps and detergents, on the other hand, have one polar end and one non=polar end. Water totally wants to hang with half of a soap molecule, but the other half needs to get out of the damn way to make more room for polar molecules. So soap molecules hide their unwanted non-polar ends in non-polar stuff lik other non-polar soap ends, air (this is how bubbles form, by the way; they’re fluid-coated soap molecules trying to keep their non-polar halves out of water’s way), and things like oil, dirt and grease while their polar ends are out high-fiving water molecules and having a grand old time. This causes little soap-coated particles of dirt or oil to break away and effectively dissolves them, like in this diagram:
Oh, and as a side note? Soaps aren’t the most prevalent things to do this. Phospholipids that make up the outside of our cells also have polar and non-polar ends and arrange themselves like this:
You’re literally made of bubbles is what I’m trying to say here.
