Playing with mud in Gulf of Bengal/Sunderbarns
When in the Sunderbarns, go to the beach and have a swim in the sea at Gulf of Bengal.Above the shoreline you will find sand, but below high-tide line, the fine materials are sedimented, so you will walk on slippery ground consisting of clay with high organic content. Adhesion of the sediment is so strong, that you can use it to play ball games in the water. But depending on the tide level you might have to struggle to get out of the water without slipping. Great fun!
