Layered water-filter science kit

Clean muddy water through gravel, sand and charcoal layers

A stacking science kit that shows how water treatment works. Three pierced tiers hold gravel, sand and charcoal, and muddy water poured in at the top drips through each layer into the clear cup at the bottom. Children can swap the layer order and see which is best.
