How long do you think you could survive without drinking any water? Only three to four days! Your body needs water to function properly. We also rely on water for cooking, cleaning and many other activities. You might not think about getting enough water if you can get it easily by turning on your faucet. But what about areas that don't have a reliable water supply? In this activity you will learn about one creative way to collect water—from the air!

This activity was inspired by a lesson from the Peace Corps on harvesting water from fog.
This activity is not appropriate for use as a science fair project. Good science fair projects have a stronger focus on controlling variables, taking accurate measurements, and analyzing data.
