Is there a way to make a sand-castle mold so that it can be used over and over again?

Yes, you can make a sand castle mold by using wet plaster of paris. First, create your desired design in the sand. Then, mix together equal parts water and dry plaster of paris. Spread the mixture onto the surface of the sand and let it sit for about 30 minutes. Once the mixture has dried, carefully remove the sandcastle from the mold and use it as many times as needed.
