This invention is a cheap and affordable method to purifying water for people who cannot get access to clean water around the world. The girls demonstrated how to purify water using the invention. They collect water from rain then put sand, stones and cotton, and tissue so it takes away germs and then a burner to take away bacteria. The water then gets measured and 5 liters is given to each family per day. This invention can also be used by people who utilize too much water to save them money.
