Water Cycle Introduction Experiment
Plastic cup, tape, water
-Put a plastic cup inside the bag and tape in place so it won't move around.
-Tape (top of the bag) the bag in a window so the bag is making a diamond shape (not square).
-Pour water into the cup about half full.
-Seal the bag.
-Watch the bag over the next few days. You will start to see a fog at the top and water pooling at the bottom tip of the bag.
