No matter what you are doing, you should just spend 8 sec on this video.
If you don't know what just happened, we got you covered. Here a hydrophobic sand is used which is essentially a beach sand( pure Silica ) which has been exposed to the vapors of trimethylsilanol (CH3)3siOH, an organosilicon. What happens is that this special sand doesn't at all get hydrated -basically it means it will never get wet. when immersed in water, it just gets surrounded by water molecule which is sheded of as soon as taken out of water.
