Human: I'm looking for information on how to make a homemade terrarium. Assistant: 
A terrarium is a container made from glass, plastic, or other materials that holds soil and plants in an enclosed environment. To make your own terrarium, you will need some basic supplies such as glass jars, soil, gravel or stones, moss, small plants, and decorations. Start by cleaning the jar(s) thoroughly and then fill them with soil. Place the stones or gravel at the bottom of the jar(s). Next, add some moss, decorative items, and plants. Finally, water the soil lightly so it doesn't dry out. You can also use potting soil if you prefer. Once everything is placed inside, you can seal the lid and place the terrarium in a spot that gets adequate sunlight.
