Let it Snow! As many parts of the the country dig out here is a fun activity. Experiment: How Much Water/Air is in Snow? Materials: Coffee mug, snow and warm room Process: Fill the cup to the very top with fresh snow. Bring the cup indoors and observe. After the snow melts, measure the amount of water in the container. Result: Most snow is 90 to 95 percent air and five to ten percent water. When the snow in the cup melts in a room above 32 degrees, it returns to water, minus the air that gave the snow its volume.
