Step 1: Using Saran wrap, cut a piece of about 28 inches to wrap on top of the jar.
Although there are many problems, many equally as great as water, in fact, we chose to focus on this as it is within our power. We realized that contaminated water is an urgent problem, and as scientists, we are curious about solving it. For anybody interested in combating third world problems here's a quick fact: 1 in every 7, or 884 million people worldwide do not have access to clean water. This is three times the population of the United states. Often, water is not even accessible, and the water that is, is contaminated with bacteria and viruses. Yearly, approximately four million people die from water related diseases which translates into a child dying of a water-related disease every 20 seconds. This comes as no surprise when bacteria such as Salmonella, E. Coli, Hepatitis B, among others are present in many bodies of water. Bodies of water from which families retrieve their only drinking water. Our group decided that our focus should be improving a water purifying device as a potential solution to combat unsanitary water worldwide. The water purifier will consist of two containers: one for the dirty water and another for the processed water. The can will be made of metal, with a transparent covering and a black exterior in order to allow and hasten the boiling process that the naturally abundant sunlight (amplified by the solar panel) will make possible.
-Black spray paint
-One plastic Tube
-A large splatter screen
-A pair of safety goggles
Step 2: Choosing the Container
For our project, we realized that there is no universal container and that the size, material, and consequently resistance varies. Based on our research, however, we concluded that 5 gallon plastic containers were pretty ubiquitous and chose to use two of them. Jerry cans as well as other containers would work as well.
