Magic Sand is regular sand with a "hydrophobic"* coating. It will not mix with water, and stays dry even when submerged! Get great lesson ideas for magic sand at our website at http://www.teachersource.com/product/....
*"Hydrophobic" means "scared of water", but what it means scientifically is that the substance will not mix with water. Oil is a hydrophobic substance.
