Recycling at it's finest.
All you need is a clear light bulb, needle nose pliers and tweezers (for removing the insides of the lightbulb and for placing your objects inside), and a few ingredients from nature.
You first put a dot of silicone on the bottom side of the lightbulb so it sits the way you want it to. After the silicone dries, layer the bottom with sand, and last, place a few sticks, stones, and/or other elements to get your desired look. Air plants work exceptionally well for these terrariums as they don't need to be watered to survive- they absorb nutrients and moisture through the air. If you don't have any of those on hand (I didn't!), use anything that you think is pretty! I put a tiny homemade birdnest in the large bulb. (I am still trying to figure out what else to put in the small lightbulb- it's opening is less than 1/4 of an inch. The large lightbulb's opening is 1/2 inch.)
Thank you, http://thehipsterho.me, for the idea and the how-to!
They got a WAY better picture of theirs (I had a heck of a time with lighting!).
