How to Make a Bottle Terrarium
A terrarium is like a miniature greenhouse. Take an empty 2-liter soda bottle and turn it into a terrarium; you will have an indoor planter that is like a miniature ecosystem in a bottle. This activity is suitable for children and adults, with minor supervision needed for one or two steps. Bottle terrariums are inexpensive to create and relatively simple to maintain, and once the plants begin to outgrow the bottle, you can transplant them easily to your garden or a larger container.
