Now this is really a neat project. Because it is an open flame, I suggest that you use these outside or purchase a glass chimney that will fit over the finished lamp. These little delights (no pun intended) could be used on your picnic table or as ambient lighting.
Below is a video that is very informative for making your little lamps and I found that the instructor left out at least two important items you should use when making your lamp. Gloves and safety glasses are a must when working with glass, especially with the thin glass of which light bulbs are made.
Enjoy and send your comments about this great little project!
