A sandcastle is a fun structure made from sand, often built on the beach. People use buckets and shovels to shape the sand into towers, walls, and moats. The best time to build a sandcastle is when the sand is damp, making it easier to mold. Kids and adults alike enjoy creating these temporary masterpieces, especially during sunny days at the ocean. Once completed, sandcastles can be decorated with shells, seaweed, or small stones, adding unique touches to each creation. While they may wash away with the tide, the joy of building a sandcastle is a cherished memory for many, reminding us of carefree days spent by the sea.
