The first step is to remove the bottom of the light bulb using pliers. This project involves a fair bit of glass breaking, so it’s a good idea to wear gloves, safety goggles, and work in a plastic bag for easy clean-up, since the glass pieces are so small.
Once the bottom is removed, it’s time to break the thick black glass. Use the pliers or a screw driver to get inside the small hole, and crack the glass. Once it's cracked, work the tip of the needle nose pliers in and break it up so it can come out. This is the hardest part of the whole the project, since you're trying to work careful so as not to break the bulb itself. Take your time and keep trying, bit by bit you’ll get it broken up and removed.
Next you need to break the inside glass part, I used a screw driver, again taking care not to break the bulb itself. You’ll need to use the pliers to break the little wires, and then shake it out of your opening.
Since the light bulbs are round and won't sit on a flat surface, use some twine to hang them. Fill with water and flowers and enjoy.
Notes
Be sure to wear goggles, and gloves since you're working with broken glass for this project. Tip: Place your light bulb inside a plastic bag while you work to remove the insides, that way the tiny bits of glass will stay in the bag and make for easy clean up.
