<human>: How do you build a homemade sandbox?
<bot>: To make a homemade sandbox, start by gathering the necessary materials. You'll need sand, water, and a container for your sandbox. Then, fill the container with sand, leaving enough room at the top to add water. Next, mix in some water until the mixture is moist but not too wet. Finally, use a shovel or other tool to create different features such as hills and valleys in the sand.
