Slick Sand truly is the closest thing to soil from Mars that most of us will ever experience. Reddish in color and very dry and dusty, Slick Sand is hydrophobic sand with the same properties as sand on Mars. It never gets wet-put it in water and take it back out, Slick Sand stays completely dry. Use it to make underwater sand sculptures, clean up oil, improve plant growth, and much, much more. Slick Sand is currently being used in NASA Mars Exploration Classroom Experiments.
