Why limit your mini-terrarium output to plain old jars? You can reuse a burned out light bulb to create a smaller, desk-friendly nature space.
Earlier this year we shared a technique for turning a wine bottle into a terrarium and we followed it up by building moss terrariums in glass jars and dishes. Now an industrious Instructables user has taken the humble light bulb and turned it into a tiny terrarium.
For the project you'll need an old incandescent light bulb, some pliers, a screw driver, and safety googles and gloves. Once you prep the light bulb you'll need some soil and some small plants like moss or clover that you want to plant inside. From there, the only care your terrarium will need is a few drops of water down inside.
Check out the tutorial at the link below for information about preparing the light bulbs and positioning the plants inside. If you have a clever plant-related project of your own, let's hear about it in the comments.
