The powder that can turn sludge into clean drinking water

When people don’t have access to clean drinking water, they can become ill or worse from water-borne bacteria and viruses, disease-causing microorganisms, and other pollutants. In DRINKING NASTY SWAMP WATER (to save the world), science YouTuber and former NASA/JPL engineer Mark Rober demonstrates how a small packet of water purifier powder can transform super muddy, contaminated water into potable water.

With only a bucket, a stick, and a clean cloth, this small packet, engineered to be a mini water treatment plant, purifies 10 liters of dirty, potentially deadly, water into clean drinkable water in only 30 minutes.

Rober talks with the powder’s inventor, Phil Souter, then teams up with Bill Gates of the Bill and Melinda Gates Foundation to discuss the benefits and humanitarian impact that results when countries with resources help developing nations in need.

Learn more about how Souter’s ‘magical’ water purification powder coagulates, flocculates, and disinfects, and how it has improved lives around the globe, at P&G’s Children’s Safe Drinking Water.

Plus, more information about the water crisis from Charity Water:

663 million people in the world live without clean water. That’s nearly 1 in 10 people worldwide. Or, twice the population of the United States. The majority live in isolated rural areas and spend hours every day walking to collect water for their family. Not only does walking for water keep children out of school or take up time that parents could be using to earn money, but the water often carries diseases that can make everyone sick.

But access to clean water means education, income and health – especially for women and kids.
