Instant Snow Experiment or Artificial snow

Can you make an artificial snow at home?. Here is a method to make instant snow using methylene blue and sodium polyacrylate. Sodium polyacrylate is a polymer which swells on absorbing water and bounce out of the cup like a snow

Reagents

• Methylene blue
• Sodium polyacrylate

Procedure

1. Take a cup of water. 
2. Add sodium polyacrylate, then water molecule will bind to the sodium polyacrylate molecule with the help of hydrogen bonds. As a result, the sodium polyacraylate will grow is size and swells much. Snow like flakes bounce. 
3. To make the "snow" blue, add 5 drops of methylene blue.

Process

Sodium polyacrylate is a polymer. Its molecule  are very long and consist of identical fragments. These fragments contain carboxyl group that absorb water-they are hydrophilic. When polymer granules absorb water, they significantly increases in volume and become visually similar to snow flakes.
