Human: I need to find out how to make a terrarium for my office. Assistant: 
You can start by gathering supplies such as soil, rocks, glass or plastic containers and decorations like plants, stones, and shells. Then, choose the type of soil you want to use based on what kind of plants you plan to put in your terrarium. Next, fill the container with your chosen soil and arrange the decoration items inside. Finally, water your terrarium regularly and keep it away from direct sunlight.
