Understanding Patterns in Water

What is the first thing that comes to your mind when someone asks you “Have you seen patterns in water?”  You would probably imagine the ripples one sees when an object is popped into the water body. Other than this one is there any other pattern you could come up with?

No??  Usually we don’t see any other patterns. When water flows from one direction to another, patterns are formed. Since water is transparent, these patterns are not visible. Let us try out an experiment to make these patterns visible.

Materials Required:

  1. Food Color
  2. A clear plastic jar with a tight lid
  3. Water
  4. Liquid hand soap with glycol stearate in it
  5. Clear tape

Procedure:

Take the bottle and add 3/4th of it with water. Put a few drops of food colour and add liquid soap to fill up the jar.

Close the jar securely. Shake it vigorously so as to make an even solution.

Make observations of the pattern when you do the following:

  1. Bottle is twirled
  2. Twirling is stopped
  3. Bottle is spun
  4. Bottle is shaked by turning the jar upside down
  5. Bottle is shaked by turning the jar side to side
