This is Eco Lantern and is the perfect example of an object with a double purpose, ideal design in saving manufacturing cost and materials.
Franklin Gaw the designer, though of designing a lantern that could function as both a light and a terrarium as well.
And he did; the lantern’s body can be filled with charcoal, pebble, soil then the plant. At daytime, you will let the plant exposed to sunlight and at nighttime, the lantern’s bulb will serve as sunlight.
When the plant grows, replant it into your back yard and wait until it will become a tree!
