Great for sand and water tables Slick Sand will not get wet! So when you pour water on it, the water will stay on top and flow, instead of wetting the sand and sinking down as happens with ordinary play sand. It is great to create moats and canals with. Once kids have Slick Sand on their tables, they won't settle for anything less! Safe and non-toxic. Includes: 1lb each of Red, Yellow, Blue, Green and Purple Slick Sand.
