(via various sources on a Google image search for light bulb terrariums)
Lately I've been seeing a lot of creative light bulb ideas floatin' around the web, whether through blog scanning, casual [or obsessive] Google image searches, or a friend sharing a YouTube video link on a light bulb project.... Hmmmm, it seems perhaps light bulbs are struggling to rise above their disposable nature through reincarnation into the world of decor!
So people, the next time one of your lamps start flickering and that light bulb dies on ya, don't get all disgruntled and flick it in the trash... Smile and whip up a little "green" do-it-yourself masterpiece! Let the new creative missions begin!
Go here for instructions on how to gut a light bulb. Here are the ideas I've come across so far:
Oil Burner

I love
this idea of turning a light bulb into an oil burner! I really like the unique bottle cap that this person used to seal the top of the bulb! And yes, suffice it to say, I'm on a new creative mission!

No doubt, the idea of using hollowed light bulbs as flower vases is compelling.... But, I have a growing collection of funky vintage salt + pepper shakers so I absolutely have to give it a go on the light bulb shakers! Check out
this page for the how-to on both of these crafts.

(frankly, I can do better... but hey, this is inspiration)************************************************Terrarium! [best idea yet!] 
As I was browsing through
Apartment Therapy just now, I came across a post on reusing busted light bulbs by turning them into mini terrariums! Ah-ha! I love the whole terrarium idea (another post that I've already begun)!!

I also found these amazing light bulb terrariums on
Etsy in a store called
Steamed Glass. These little habitats are nothing short of art!
Aaaaaand.... Concrete Wall Hook Mold? :)

Just when you though you'd seen all the light bulb ideas.... A concrete light bulb wall hook! Not my taste, but a crafty idea nonetheless. For instructions on how to create your own concrete light bulb wall hook, visit

************************************************Well, that's that.. I'll post more light bulb reuse ideas as they come my way. Oh, and as tempting as it may be to just go out and buy one of those fascinating ready made little terrariums, isn't it more interesting to see the results of ones own imagination when put to this new creative test?? Light bulbs are easy to come by so there's really no excuse for not experimenting... :)
