Half fill a small glass with water. Add some soil
and oil and stir it till it become a brownish
colored mixture. This will be the “dirty water”
used in the experiment.
Pour some prepared “dirty water” mixture into the
top of the filter column very slowly. The water will
trickle slowly down through the filters.
There will be water remains in every observation
section before they drip off into another filter
column. Compare the result of each observation layer
and you will see the different functions of different
filter materials.
*Warning: The filter column is not
intended as a filtering device for
drinking water. Do not drink the filtered
water.
