A sculpture made of sand and resembling a miniature castle; typically, but not always, made for fun by a child on a beach. quotations examples
Children learn the importance of water in soil mechanics from an early age. They learn on the beach while making sandcastles. When they use dry sand, their castle flows into a heap even as they lift the bucket. The particles of sand have no cohesion and little friction between them.
