Yes, the title of this blog post is true and i will show you how you can make salt like water popularly known as "Dry Water". Its is a Scientific topic that we will study today. 
Dry water by its name is completely dry with zero moisture, 50% less dense, hydrophobic in nature that will not wet your hands when you take dry water on your hands. But its exactly opposite to what we know about water. Let us see what is the science behind it and how to obtain it.

Dry water is a mixture of water-air emulsion(means two liquids that do not mix with each other like oil) that contains tiny water molecules completely separated with each other coated with sandy silica.
Let us understand dry water with a example. Consider sand which contains water but the molecules are grains of sand that isolates water by its true nature and does not wet things up. The sand molecules do not penetrate the hand gloves and does not wet the hands because they are not small enough to penetrate(get inside).

The objective is to separate water molecules into large silica molecules. We will use emulsifier like fumed silica to mix it with water with a very high speed (about 19000 rpm) for about 90 seconds. After mixing, mixture will be obtained.
Let us have a look at some properties of fumed silica
  • It has the lowest density about (1% of water)
  • it is Hydrophobic in nature(does not mix with water)
  • 50mL of fumed silica weighs only 1.9gm whereas 50mL of water weighs 50g
  • It is white in color
Applications 
  • It is used to dissolve harmful gases
  • It is an effective method for reducing carbon emission by trapping CO2 in dry water cylinder
  • 3x more effective in capturing carbon emissions than regular water exposed for similar time 
  • It is a excellent way to transport gases by adsorption
