Lightbulbs and Aloe Gel

Remember my lightbulb TV screen?I've learned some important lessons about liquid filled lightbulbs since I made it.
First, if you use binder wire and the wire goes into the liquid it will start to rust and make the whole thing turn a disturbing brown colour.

I am still using binder wire to hang regular-sized bulbs, but now I am wrapping the wire around the outside of the threads and applying some solder.
I am also trying a new liquid, aloe vera gel. I think it might look cool because air bubbles in the gel don't seem to move.

ooooooo. that DOES look cool!

It looks cool, indeed. And, if you have a cut or burn, you could empty the contents of one of the bulbs directly onto the wound.

It's funny that you mention that, Aggie, because I have cut myself while working with lightbulbs and it never occurred to me to use the aloe gel.

Woah, that looks mental.
How do you get the gell into the bulb without breaking the glass and still keep the bottom on? Magic?!

David Scrimshaw said...

On the very bottom of the lightbulb, there is a bit of metal that I pry off with a penknife.

This leaves a hole in the black glass that sticks out of the threaded aluminum. I stick a nail in the hole and crack the black glass. Then I use needlenose plyers to remove the inside bits leaving a glass bulb and the aluminum.

After filling with gel or other liquid, I use caulking to seal the bulb.
