Human: How can I make my own terrarium? Assistant: 

1. Start by gathering supplies like soil, gravel or stones, moss, plants, and decorations such as figurines or glass beads.
2. Place the soil in a container that is at least twice the size of your chosen plant.
3. Add your decorative items to the soil and press them down gently.
4. Place the plants you have selected into the soil.
5. Fill the remaining space with more soil until it is level with the top of the container.
6. Water the soil lightly and keep it moist but not saturated.
7. Place the lid on the container and secure it tightly with screws or other fasteners.
