Today's question, arose after myself and Shashu were discussing how much fun we have playing in the beach. Following this he asked me the million dollar question that, "Amma, why should I take bath after playing in the beach?",to which I casually replied, to wash off your stickiness, which is caused due to the salt water. Several rivers come join the sea, carrying salt and minerals from riverbanks, resulting the sea water to get salty. It is from the sea that we get salt, which is taken from the seawater after drying the water in specified areas and evaporating the water, leaving behind the salt. This salt is purified and used by us for cooking and other required purposes.
