Hello Again! I have made great progress on my water filter. I have finished building part one of my water filter and heater. This weekend, I spend a few hours crushing charcoal and building my filter. I first cut the bottom off a 2 liter plastic soda bottle. I filled it half way with pebble sized charcoal, and I filled the rest with sand. I also cut a piece of cloth to use as the initial filter.
I had some difficulties initially with crushing the charcoal. I first tried to crush it by force. When that did not work, I used a hammer. The hammer works, but it creates a lot of dust and little pieces
I have learned that if I persevere, I will eventually succeed. The next steps in my project include testing to see whether my filter works before moving on to building the solar water heater.
I am getting closer to my ultimate goal: creating a simple way for people in developing nations to filter their water without kerosene or fire. I recently talked to my grandfather, who built water treatment plants in India. He recommended adding in a sand layer and to use reverse osmosis to get rid of the chemicals that charcoal and sand cannot filter.
I can apply what I have learned to my everyday life. A lot of the skills I have learned, such as using a drill bit, hammer, and other tools, will be useful in the future for other projects. I have also learned about hard work, perseverance, and not giving up.
