When I was growing up I had a keen interest in the sciences.

I made a number of small boilers in order to learn about steam and distillation.

I hope to show people that even if a bulb burns out, it can still be useful.

Step 1 You will need some common tools, a screwdriver (regular) and snips (or needle nose pliers). *CAUTION* Never use a fluorescent bulb for this project, no matter how cool it looks.

The powder used to coat the inside of them is made from phosphor and is quite toxic.

You’re also working with glass, so use eye protection! You should also use gloves or wrap the bulb in a towel just in case it breaks.

Yeah, you can’t see mine because i didn’t have any handy. Step 2 First, grip the little solder point and give it a good twist.You will free the brass contact and break one of the wires leading to the filament.Step 3 Once the contact has been pulled out, carefully crack the glass insulator.The chips from this are quite pervasive, they get into just about anything in the area and they are razor sharp. Step 4 After the insulator has been removed you can see the inside supports of the filament and the fill hole.In the old days bulbs were evacuated of atmosphere to keep the filament from oxidising and burning through.Now days the glass envelope is back filled with an inert gas like argon.
