What is magic sand in science?
Magic Sand is regular sand that has been coated with an oil-like substance so it is water-hating. The Magic Sand grains like to stay in contact with each other. Also, the surface tension of the water makes the Magic Sand float. Making Magic Sand Wet.
Is magic sand any good?

Why does magic sand not get wet?
‘Magic sand’ has a special coating that prevents water from clinging to it – that is, it makes the sand hydrophobic (‘water-hating’). When ordinary sand meets water, the water clings to the sand, getting it wet and making the grains stick together. However, water rolls right off magic sand, so it doesn’t get wet.
Why does magic sand clump?
Unlike normal sand, magic sand has a hydrophobic surface that repels water, so it does not get wet. Instead, magic sand clumps together under water and behaves unlike normal sand.

What is mystery sand?
This hydrophobic (“water fearing”) sand is coated with a silicon compound. The layer is only one nanometer thick, so the coated sand looks and feels like regular sand, but it behaves very differently. Hydrophobic sand was invented to clean up oil spills. It repels water but attracts oil.
How does magic sand keep the sand dry?
However, “Magic Sand” begins as normal looking sand, until it’s coated with a substance that repels water. This special coating keeps the sand dry even after it has been dumped into a container of water.
What makes Magic sand float in a cup of water?
Also, the surface tension of the water makes the Magic Sand float. Pour a small amount of Magic Sand in a cup of water. As expected, the Magic Sand stays dry. Add about 12 drops of liquid detergent to the water and use a spoon to stir the mixture. Soap breaks down the oil coating on the sand and lowers its hydrophobic properties.
