water cycle model with spray bottles

This water cycle model can be used in a variety of ways for student experiments. It can be filled with water and closed to be used to simulate the phases of the water cycle over a few days (with a lamp to heat the water). It can also be used as an open model to show the pathways that water travels through, as it flows to the ocean.
