Filtering water / science

The goal of the experiment - To filter water with simple items.
equipment:   bottle, 2 plastic bottles, paper towels, string and cotton balls





what we noticed- the water was still a bit murky so we are going to re filter it again till its clear.

what we changed- we loosened the rope to make the water drain faster.

What we should've done: we shouldn't  of put the cotton balls in it because it soaked up some of the murky water.

Conclusion, Our filter ended up working very well we ended up filtering all of the sand and mud but the water turned yellow.
