Well the story behinds these set of photos is rather amusing!...
I used Red nail polish...as nail polish does not blend completely with water...some were smudged , but I did get a few that were intact drops in the water. In the other picture, I smeared some blue toothpaste and put a few drops of nail polish on it to give it the contrast.
I am glad I decided to use what I used as these things have a certain consistency , which the normal water colors do not, anyways I could not find my water color set that day.
