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 Pour a small amount of Magic Sand in a cup of water. As expected, the Magic Sand stays dry.
What does the fabric protector do to the sand that makes it hydrophobic? Why does the oil sink? Why does the sand stick so close together? Most people associate sand with the ocean.

The dry patch is evident as the thin reflective film of water at the surface surrounding your foot is no longer there and has instead been drawn into the bulk of the sand beneath your foot. This drying of the sand underfoot is referred to as the Wet-Sand Effect. The effect results from the dilatancy of the media. Here the volume of the sand ...

In this video, you can see the experiment in which a sledge with a 1 kilogram weight is dragged over dry sand. A pile of sand accumulates in front of the sledge.
If desired, the experiment can be extended to isolate dry samples of sand and salt. To do this, the damp sand in the filter paper can be transferred to another sheet of dry filter paper, and, by folding and dabbing, the sample can be dried. If necessary, another piece of filter paper can be used.
Dry sand doesn’t stick together or form clumps; instead it flows almost like a liquid. If you pick up a fistful of dry sand, it’s hard to keep it from streaming out between your fingers. But if you add a little water to dry sand, it suddenly becomes packable and moldable.
