There is a little girl who lives with her family in Africa. Her and her mom walk hundreds of miles a day, going back and forth to get water but it is still not sanitary to drink. Sometimes they don't have time to boil or even have the things the need to boil the water to get it clean even then is isn't safe to drink.
Then one day and American traveler was visiting Africa and noticed the water they wee drinking was unsanitary. that is when he got to thinking how could he make a water purifier that they can use here in Africa. So he started experimenting to see what would work and not be that expensive. When he finally came up with a solution he told us scientist about it and got to making it so more people could use them.
They got to making hundreds of little packets of them and started to send them over to Africa. the American Traveler explained that what you do is open the little packets and pour the powder into the water and mix in and let it sit. The little girl was so happy that now she can drink the water with out getting sick and was very excited. The other way the traveler came up with was to dig deep deep wells that found naturally purified water which helped a bunch of the families there in Africa and other places that didn't have clean water
