Students at the University of Virginia have developed a new way of purifying water that they say could bring improved water quality for millions in the developing world.  It’s called a Madi Drop. Field testing begins this month in South Africa.

The lab operates like a kitchen. They add several ingredients. Then they mix, weigh, press and bake them.

What’s created is called a MadiDrop – a ceramic disc infused with silver.

When dropped in water, silver ions, which are atoms that have an electrical charge,, are released to purify the water.  And, testing here at the University of Virginia shows clean, safe water.
