Meet the innovative TUBAN water-repellent sand, which repels water without bonding with it. The sand is coated with a special layer that keeps its grains dry, even after contact with water. The sand can remain in the water for a long time, and when taken out, it is still dry! The hydrophobicity is an extremely interesting phenomenon that can be explored by playing with TUBAN sand and water.

Discover how, thanks to water-resistant sand, you can save the oceans from pollution, build underwater shapes, and become a magician by pulling dry sand from the water.

The set includes:

• water-repellent sand in 5 vibrant colors
• measuring cup for pouring and removing the sand
• water container

Main instructions:

• fill the container with water up to 3/4 of its height
• with the measuring cup, pour sand into a container of water, creating any shapes
• you can mix the shades of sand as you wish
• observe how the sand behaves on the surface of the water and how it sinks
• try to scoop the sand out of the water with the measuring cup and see what happens

Do an experiment and see for yourself: pour different shades of sand into a container filled with water. Create and observe the various shapes it will make. Then, pull the sand out of the water and see that it is dry! You can also pour sand onto a plate and add a few drops of water. See what happens then!
