I know, I know, there are already two instructables (to the best of my knowledge) about making a light bulb aquarium, but mine has step by step instructions with pictures for every step
Step 1: Get your Materials
you will need:
1 globe light bulb
1 coat hangar
1 4" long peice of 2x4
.25 lbs of aged aquarium gravel
1 bottle water conditioner
1-3 ghost shrimp
1 pair of needle nosed pliers or tin snips
1 screwdriver, or skinny scissors
Step 2: Copper Connector Removal
Use your needle nosed pliars or tinsnips to remove the copper connector on the end of the light bulb
Step 3: Break glass
On the end of your lightbulb, there is black glass. The best way to get that out, is to put your screwdriver or skinny scissors into the little indention where the copper connector used to be, and twist back and forth to crack the glass. Be careful, the glass shards are extremely sharp, and extremely painful once they are lodged in your hands.
Step 4: Break Glass
After you have removed all of the black glass, look into the stem of your lightbulb. You will see two things. A skinny long tube, and glass covering the stem. Point the stem away from yourself, and gently, with the screwdriver/skinny scissors, break it. It is pressurized, and will, on ocasion send a shard flying. then you can insert the tip of your tool, and give it a gentle rap with your hammer to break the glass that seals the lightbulb.
Step 5: Remove protrusions
Remove the extra points and protrusions on the inside of the stem.
NOTE!: do not attempt what i am doing in the picture. It is extremely stupid, but it was the only way i could illustrate the point that there was a lack of obstructions in the stem.
