The best way to prepare a sand castle is to start by gathering all of your supplies. You will need sand, water, and a bucket or container for mixing the sand and water together. Next, you will want to decide on the design of your castle. Once you have an idea, begin creating the walls by using shovels or spoons to shape the sand into the desired shape. Use your hands or small tools like toothpicks to create details such as windows, turrets, and other features. Finally, use water to help bind the sand together and make sure it is sturdy enough to last throughout the day.
