Why don't oil and water mix?
Water is what they refer to as a very "polar" molecule. That means it has a "electrical charge" associated with it. Sort of like a magnetic.
Oil on the other hand has no charge, it's completely neutral.
Now if I take two magnetics and put them near each other, they'll bind together. Water molecules behave the same way. Because they're little magnets they'll "bind" together.
So when you mix oil with water, all the water molecules get attacted to each other and essentially "push out" all the oil molecules, causing the separation you see.
i hope that helps
Thank you Kristi, I really appreciate your response.
