09_Make Your Own Water Filter Experiment

I made my own water filter, Do you think it will work? Here's what you'll need, An empty 2 liter bottle cut in half by a product, water, dirt, sand, gravel or small rocks, cotton balls. First, I added dirt to make my water dirty. I put top half of the bottle inside the bottom half. I put cotton balls in neck of the bottle. Then I'll put in lots of sand and a few handfuls of rocks. I'll put my dirty water to the filter, the dirty water will move of the layers. Did my experiment works? The bits of dirt in the water were too big to pass through the sand, and the cotton balls. So, the water got through is much cleaner now this water is still isn't safe to drink. But I can use it to water plants. My water filter really works. Now, you try it.
