What You Get

Test tube of hydrophobic sand. Includes 60g of Hydrophobic colourful sand in a plastic test tube. Detailed instructions and science ideas included. Colours vary. A random colour will be delivered unless specified in your order comments.

How does it work?

Hydrophobic sand starts out as normal sand but is then dyed and covered with a water-repelling polymer that keeps it dry. Pour the magic sand into a small container of water and watch it float, clump and sink. Because of its water-repellent properties, when the sand is poured into water it holds its shape and can be moulded into interesting structures under water. Pour the water off and the sand is still dry, ready to be used again and again.

Hydrophobic chemicals have many practical applications - such as creating water proof suede shoes or mud resistant construction site boots.

Compare this hydrophobic toy with our contrasting hydrophilic toys (water-loving!) like instant snow and growing spheres.
