Prototype Reflection

The objective was to make a water filter with supplies you would find on an deserted island. Me and my group made a water filter out of a water bottle, a piece of cloth, some fine sand, rocks, and steel wool (which replaced charcoal but did not have the same purposes. This is a picture of the water filter we made.The bottom layer was fine sand, the middle steel wool, and the top is small rocks. There was a piece of cloth wrapped with rubber bands in the bottom.
