To help preserve the environment, we can equip our homes with energy-saving light bulbs. Here is an opportunity to recycle old light bulbs into trendy hanging vases or salt and pepper shakers. These airy glass spheres can be poetically transformed in a thousand and one ways...
Here's how: Saw off the bottom of the light bulb screw base using a hacksaw, turning the light bulb evenly. Bulbs with a bayonet base can also be used - in this case, saw off the bottom of the base along the apparent line. Once the base has been cut, insert a thin screwdriver and break the protruding tip of the glass mount, or stem, that holds the filament (be sure to protect your eyes). Then, using a bigger screwdriver, insert it into the glass socket, and give a quick, hard tap to break off the remainder of the mount. Using a rounded file, enlarge the hole and remove the filament. Your light bulb is now empty.
To make a hanging vase, use a gimlet or hole punch to pierce a hole on either side of the light bulb base. Aluminum is very easy to pierce. With a thin piece of wire, create a hanger. Pour in a little water and place a flower in its new home.
To make a pair of salt and pepper shakers, hollow out two light bulbs. Protect the light bulb with a piece of cloth and, using a small hammer, lightly flatten the top of the screw base. This will ensure that the caps fit securely. Find two old plastic soda bottle caps and use a knife to remove the plastic disc lining the cap. Then, pierce several holes into the cap using a large nail. A circle of thick felt or wooden rings glued to the bottom of the shakers will stabilize them. Fill with salt and pepper, and then screw the caps on.
