- Water Bottle
- Scissors or Knife
- Coffee Filter, Cotton Balls, or fabric.
- Sand or charcoal
- Large gravel or small rocks
- Cup to hold filtered and non-filtered water.
In my case i used a small screwdriver and easily made a nice hole in the center.
A knife or scissors work just as well.
Your water filter is now complete! Just put the filter over your cup for filtered water.
With the other cup, pour the dirty/muddy water into the filter.
