The last step is to put something heavy right in the center of the plastic wrap, over the empty glass. That will weigh the plastic down and help you collect the water. Now you''ve made a solar still. It''s called a still because it distills, or purifies, water. Leave your still outside in the sun. Leave it alone for a few hours, or even a whole day.
