Currently, the Lower Filter portion of the team is working with a recent shipment of new supplies including a collapsible, 3.5 liter plastic container. We attempted to apply pressure to the container evenly via adjustable straps that can also be fashioned into a tourniquet. The container responded well to the pressure, something that we had been unable to do with our previous design. Our next step will be to create an exit passage through which the water can flow and then add a filter to that system. One of our challenges will be creating a pathway through which the water can circulate. We plan to do this by attaching a piece of plastic tubing to the container; the tubing will have one-way valves that allow the water to flow in one direction only. We will be continuing with this idea next week.
