Great for wealthy kids to learn about water evaporation and condensation… or poor developing countries where clean water is a real concern. The WaterCone is a simple and neat way to turn brackish or salty water into potable drinking water.
Or you could always get the Watermill or the Lifesaver water purification gadgets.
1. Pour salty / brackish Water into pan. Then float the Watercone® on top. The black pan absorbs the sunlight and heats up the water to support evaporation..
2. The evaporated Water condensates in the form of droplets on the inner wall of the cone. These droplets trickle down the inner wall into a circular trough at the inner base of the cone.
3. By unscrewing the cap at the tip of the cone and turning the cone upside down, one can empty the potable Water gathered in the trough directly into a drinking device.
