Please help me to make a water filter?




So i have sand gravel cotton balls and coffee filters. I have to put those into a cup. At the bottom of the cup there is a hole. You pour water into the cup then the materials filter the water to make it clean. I am asking what order should they go in and i have 2 coffee filters and can you put them in order from top of the cup to the bottom of the cup.

This is for a science (specifically Chemistry) lab we were doing. Our teacher brought out a beaker with a muddy mix of water and dirt, telling us to try and seperate the dirt from water and produce as much pure water as possible. We have access to all the equipment at school, like the bunsen burners, beakers and such. He instructed us to create an original way to filter out the dirt. We are allowed to bring materials or supplies from home, although he suggested not to bring coffee filters as that isn’t very original… and I have been brainstorming with no conclusions. Any suggestions or cool ideas?
