This is weird stuff. Like teflon water won't wet it. Water beads up on top of it and will not be absorbed like with regular sand.
If this sand is sprinkled on top of a water surface, it will stay on top until it is heavy enough to break the surface tension and form a blob that sinks to the bottom. It looks weird because it doesn't wet and carries air too. It forms strange shapes.
When it is scooped up with a spoon, water breaks away from it at the surface, and the sand is completely dry.
Another interesting observation is that these particles attract one another when sitting on the water surface. They deform the surface and can reduce surface area/ energy by coming together. As the particles come together, they form fractal like structures.
