Human: What are the best ways to prepare a sandcastle? Assistant: 

1. Start by gathering your supplies – buckets, spoons, water, and sand.
2. Mix up some wet sand and water in one bucket and then add more water as needed until you have a thick paste-like consistency.
3. Divide the mixture between two or three other buckets.
4. Add a spoonful of dishwashing liquid or white vinegar to each bucket.
5. Slowly pour the sand/water mixture into the buckets, stirring continuously with the spoon.
6. Use the spoon to create different shapes and structures within the sand castle.
7. Allow the sand castle to dry completely before adding decorations such as shells and seaweed.
