Materials: funnel, aquarium charcoal, 2 small beakers, food colouring, non-absorbent cotton, ring stand
Place a small piece of non-absorbent cotton in a funnel. Fill the funnel with aquarium charcoal, and put a small beaker beneath the funnel. Fill a second beaker with about 25 mL of water, and add five drops of food colouring. Pour the coloured water through the funnel and collect it in the beaker beneath as shown in Figure 2.
Compare the colour of the filtered water with the original coloured water. Predict what will happen if the water is filtered once again. Test your prediction. How would you improve the filter?
