What is reverse osmosis?

Imagine if you could take a bath in a giant machine that turns yucky water into the cleanest drink ever! Look at that big jar of DIRTY WATER—it's filled with hidden salt and bits of dust that we definitely don't want to drink. But then, the WATER PUMP starts workin'! It squeezes and PUSHES that water through the pipes like a super-strong hug, forcing it toward a secret doorway. That doorway is the FINE MEMBRANE. It's like a magical screen with holes so teeny-tiny that only the smallest water drops can wiggle through. Because those salt bits are too big and chunky, they get TRAPPED! This BLOCKED SALT has to go another way, leaving the water totally fresh. Finally, out comes the PURE WATER—sparkly, clean, and ready for a big gulp! It's like a tiny car wash for every single drop.
