Discussion:
The water became cleaner than before because the impure particles couldn’t fit through the filter paper, but the water could because it has finer particles so it would get through the filter paper. The water smelled weird and tasted a bit dirty but it looked pretty clean. The filtering did take a long time due to how much dirt we added to the water. We only filtered it once but we still drank it mainly because it did look clean and by it looked clean I mean it was clear and didn’t have any dirt that I could see.
