How can I make a terrarium to put on my windowsill?

To make a terrarium for your windowsill, you will need some glass or plastic containers with lids, soil, gravel, and plants. Start by placing the container in the window so that it is facing south. Place the soil and gravel at the bottom of the container. Next, place the plants around the outside edge of the container. Fill the rest of the container with more soil and gravel. Finally, water the soil until it is saturated.
