Pocket Size Bio Sphere

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. 

Step 5:

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.

Step 6:

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.

Step 7:

There it is, my Pocket BioSphere.  Thanks for looking.

    Yea, I was a little skeptical when I saw that you were using a light bulb. They tend to be quite fragile. I'd recommend using something like a perfume bottle or something made of thicker, less disposable, higher quality glass.

    I really like this idea! I think I will make one soon. Only thing I would say is that it would be nicer to have some clearer pictures. These are a little fuzzy! Good job besides that! :D


    This project is really cool, is there anyway that you could change your intro image to be a bit clearer? Thanks!
