What makes the water the cleanest, stones, fabric or stones and fabric?
We think that the fabric and stones will make the water the cleanest.
You will need: 2 see through cups, 2 pieces of fabric, 15 stones (mix of small, medium and large), table spoon, small cup of mud, small cup of sand, table salt and a map pin.
- Pierce the cup 17 times with the map pin then put the stones in to one of the clear cups.
- Put two table spoons of mud salt and sand in to the cup with the stones.
- Next put the cup with the stones and mixture in to the other clear cup.
- Fill the cup to just past the mixture.
- Wait until all the water has passed through to the second cup and take a picture of the cups on a white background.
- Wash up your cups a start the procedure all over again with fabric and then fabric and stones.
The fabric and the stones made the water the cleanest and then it was the fabric then the stones.
It would be great if you could add photographs of your filter so that we can see it.
