Question

Can you design a simple water filter using everyday materials? What would you include and why?

✓

Answer

Yes, a simple water filter can be designed by using everyday materials that are easily available.
Hint: We can use a plastic bottle, sand, gravel, charcoal and a piece of cotton cloth.

First, we cut the plastic bottle in half and placed the top part upside down like a funnel. Then, we tied a piece of cloth over the mouth of the bottle. Inside the bottle, we layered the materials in this order: fine sand at the bottom, then charcoal, followed by coarse sand, and finally gravel on the top. This setup was placed over a container to collect the filtered water.
When muddy water is poured in, the gravel traps large particles, sand removes dirt, charcoal filters harmful chemicals, and the cloth catches fine impurities. The filtered water appears much cleaner, but it should still be boiled before drinking to make it safe.
