"BOTTLES, ANTIQUE: Would you believe it! There's old-fashioned glass bottle shapes inside of light bulbs...different bulbs have different shapes. Caution! Practice good safety! Protect your eyes and hands when working with broken glass!!"
I found this at http://dollhouseminiaturesclub.freeservers.com/tipsaf.htmWe've already switched over most of our bulbs to the new compact fluorescents, but I did still have a couple old bulbs laying around. I didn't have any gloves or any glass cutting tools so my first attempt was kind of messy. I'd like to get some sort of glass cutting tool and also one of those crystal savers to file down the sharp edges and then try this again. On another note I did find a neat website that tells you how to hollow out a light bulb (you would not want to to this if you were trying to keep the piece inside b/c you have to break it to hollow out the bulb) http://www.teamdroid.com/diy-hollow-out-a-light-bulb/. And here's a neat pic where somebody hollowed out bulbs and used them as flower vases. http://www.craftbits.com/viewProject.do?projectID=886. I'm definitely going to try this next b/c I think it's a great way to recycle used bulbs and it would look pretty hanging in a window.
