This Hydrophobic Sand in a Test Tube is a great way to teach about the properties of hydrophobic substances and their interaction with water. And just fun to play with too!

Simply pour the Hydrophobic Sand into a cup of water, watch how it reacts with the water. Using your fingers or a spoon, mould the sand in the water into different shapes. When you are finished, simply remove the sand from the water with a spoon... it is perfectly dry! Store in your Test Tube container, ready for the next time.

Hydrophobic Sand is regular sand which has been dyed and coated with a hydrophobic substance - a substance which repels water. The coating on the outside of the magic sand repels water and keeps the sand dry!

The Hydrophobic Sand Test Tube comes in 3 colours - pink, blue, and green. Colour is chosen at random, however, if you have a preference please put this in your order comments and we will do our best to fulfill your request.

A little gift that got a big ‘Wow’. My kids definitely thought this was pretty cool. It generated lots of questions, conversation and creativity too. They found it both intriguing and fun to play with. Bit tedious to get back into the tube when finished is the only problem.
