Refine the design
Our design actually did exceptionally well on its trial run and because we liked our results we decided, instead of developing a new design we should double our old one. We then took all of the layers we previously had and created another filtration section in the water bottle. As a final additive we placed charcoal on the vary top of the bottle. This helped with filtration but gave enough time for the charcoal particles to be filtered out.
Results
Test 1: 20.5 ntu
Test 2: 28.9 ntu
Test 3: 19.5 ntu

conclusion
In this project, we had to design a cheap and durable water filter for third world countries. In order to achieve this goal, we had to brainstorm the ideas from what we learned during researching. Then, we tested some materials to determine the turbidity. From what we gathered, we create the prototype from best effective materials. Then, we tested that and evaluate for better result. I personally felted that researching is the most important part. Because, we don’t have worry about failure since we have more ideas not just one. I think one more day would be nice to complete all of the deliverable.
