Design Plan
- We are using Tinkercad and a 3D printer to build our design.
- It will consist of two spheres. One will fit inside the other. The inner sphere will be the filter for the water.
- The dirty water will fill the inner sphere, and as it rolls, the water will filter through to the outer sphere, where the clean water will remain uncontaminated emptied.
- There will be a pipe connecting the inner sphere directly through the outer sphere, so the clean water does not have to come into contact with the outer sphere, which at one point contained the dirty water.
- We will a filter to clean the water. This filter consists of a coffee filter, sand, and water activated charcoal.
- Coffee filter: Filters out large particle.
- Sand: Catches smaller particles that are not caught by the coffee filter.
- Water activated charcoal: Removes the harmful bacteria and toxins from the water.
