Water and sand

This colourful sand is dyed and coated to repel water, so it's always dry, even when it’s submerged! Scientists would say that the sand is ‘hydrophobic’, which translates as water fearing. You can mould this hydrophobic sand into structures under water, and then simply drain off the water to reuse the sand.

For your chance to win a test tube of hydrophobic sand from www.entropy.com.au, send us a tongue twister you have made up about sand.
