Abstract
This is a written version of a popular science talk for school children given on India's National Science Day 2009 at Mumbai. I discuss what distinguishes solids, liquids and gases from each other. I discuss briefly granular matter that in some ways behave like solids, and in other ways like liquids.
5 pages, eps figures, written version of a public lecture given at Mumbai on Feb 28, 2009
