In this video, we learn how to purify muddy river water. First, take a bucket of dirty river water straight from the river. This will be in a 2-5 gallon bucket. Now, add 1 packet of water Purifier per every 2 gallons. Stir this in for 5 minutes, stirring constantly. Once the powder has been in the water for a full 5 minutes, it will purify the water and the dirt will all go to the bottom of the bucket! This is being used in Haiti where an earthquake destroyed the homes of many people who now have no clean water to drink.
