This project investigates which combination of simple filtering materials like cotton, sand, and gravel can clean dirty water most effectively. By building different bottle filters and comparing the clarity of the filtered water, the study demonstrates how layered filtration works and explains how similar methods are used in real-world water treatment systems to provide safe drinking water.
I like the idea. very impressive work!
