There’s so many cool light bulb projects out there. You can turn a disassembled bulb into a terrarium, aquarium or a Christmas ornament for example. So when a light bulb recently blew out I knew I had to recycle it into something neat. Today I will show you how to hollow out a light bulb in just 5 easy steps. Trust me it’s super simple and even my clumsy self managed to disassemble it without breaking it into a thousand pieces.
Here’s what you’ll need:
Yup that’s all!
Let’s get started 🙂
Wrap the bulb in a towel so you’re safe if it shatters. Grab the solder point and twist it until it comes off.
Once you pulled out the contact you have to crack the black glass insulator. The chips from this are charp and fly around everywehre. Be very carfefully while removing it. You might need some pressure. After you removed the insulator you can see the inside supports of the filament and the fill hole.
Use a screwdriver to break the fill tube. You can now shake the filament assembly out of the tube.
There will be sharp edges left. Try to remove them as best as you can and be careful while filling the bulb. By the way excuse my messy nails. But I’d rather paint them after a craft than messing them up again :p
The bulb needs a cleaning. I used water but salt seems to work too. Some bulbs are coated with a white powder (Kaolin). It’s not too dangerous but still be careful and keep it away from anything important. And you’re done!
I turned my first holowed out light bulb into a light bulb aquarium! I love it so much! What did you make out of your recycled bulbs?
Great tutorial! But please tell me you’re talking about aquatic plants only when you say “aquarium” – a light bulb is much too small for any fish to live in. 🙁
TabzillaBlue yes I am. I will upload the tutorial for it this weekend. I actually own a tank and would never hold fish in a light bulb! I even think holding a beta in a small bowl is super cruel and its forbidden here in Germany.
That’s really cool! I’m looking forward to that tutorial. 🙂
Great tutorial! I’ve never actually thought about how to dis-assemble a bulb. I wonder if doing it with those huge globe bulbs would be the same. They would look awesome too!
Oh that’s a great idea! If you do it please share a pic. Would love to see the result 🙂
WOW this helped me quite a lot since i am making a diy book , and trying to collect as many cool and interesting things as i can. : )
Great! We’re glad you like it! If you use our Idea please make sure to give us credit 🙂
