"Woo hoo! What can I do with these?!" I thought. After perusing Pinterest, I decided to make flower vases out of them. I mean, I will have a rediculous amount of flowers soon anyway.
I started with an old bulb, a tiny nail and my (rusty) pliers. 
The first thing you need to do is pull what looks like a thumbtack out of the center. (Make sure to do this over newspaper so that you can gather all of the debris and throw it away when you're done).
Once this is out, you'll see a tiny hole. Insert your nail (or bobby pin) and wriggle it around until the black glass cracks. Tack your pliers and pull out all of the black glass.
Wait, the bulb isn't hollow? Nope. Sure isn't. You'll want to pull out the two wires you'll see in there. (Oh - be sure that, when gripping the lightbulb with your opposite hand that you're gripping the metal part. Our tendency is to squeeze or grip firmly, and if you're holding the bulb end, off to the ER you'll go.) 
Ok, here is where you exercise some patience. Stick one half of the needle nose pliers in the bulb and gently yet firmly press until you hear the inside glass break. Shake all of the guts out.
Get a pen (or wire, whatever you have handy) and a paper towel. The bulb is actually clear with a white powder coating. Poke the paper towel into the bulb and swirl it around, wiping down the edges. 
Shake out more guts. I rinsed mine with warm water and let it air dry. On a side note, I had some foil wrapped wire from a party that I worked, so I used that as the hanger. Have fun!
