Forward osmosis

Forward osmosis is a process that helps move water from one place to another. Imagine two buckets of water - one with salty water and one with fresh water. Normally, the water will just stay where it is, like a wall is stopping it from moving. But when forward osmosis is used, the fresh water moves across the wall, or the salty water, to the other side and fills up the other bucket. This happens because the salty water has a lot of tiny particles inside it, and they want to push the fresh water through the wall. The particles make a pathway for the water and help it reach the other bucket.
