I had just built my bedroom shop and wanted to make something. So I found a lightbulb (blown) and started my first project. I drew what I wanted it to look like so I would know what materials I would need.
Step 1: Materials
1 globe style clear light bulb
for cutting off base of bulb
Step 2: The Bulb
First I had to remove the base. Then the filament. Gently remove the rough edges.
Step 3: The base
I used a spare piece of wood. Measured to fit the bulb and chiseled a bowl for the bulb to sit in.
Step 4: The Cork
I couldn't find a cork to fit the opening so I improvised. I took an eraser and cut a piece off and shaped it to fit the hole.
I stole some dirt from my mom's "weeds", um, houseplants. I used an eye dropper to add water to clean the sides of the bulb, then used it to remove any excess water.
Back to mom's 'weeds' and pick a couple of plants. One is a klanchoe (sp?) and the other is a spider plant. I had to use a skewer to get the plants into the bulb. I added a few stones to finish the look.
There it is, my Pocket BioSphere. Thanks for looking.
