This amazing sand has the same properties as the soil on Mars, so it stays completely dry, even when immersed in water. Ideal for hands on investigations, this non-toxic sand can be moulded and formed into shapes underwater. When the sand is lifted out it is totally dry and can be used again and again. The sand is actually coated with a silicon which makes it hydrophobic (water hating). Age: 3 years+.

• Box size: 130mm(w) x 132mm(d) x 135mm(h)
