Exploding light

[Eric Krewson]

I was filling a gap in a project with super glue and sawdust, pulled and incandescent light over the fix to see it better and the light bulb exploded. I suspect the super glue fumes caused the bulb explosion.

I won't try the same thing again to see if it was the fumes, they are pretty rough on anything they touch. Just a heads up.

Good cautionary tip, Eric. I think there is a good chance you are right.

Thanks Eric.
Good thing you were not testing the draw when it blew.
I was pulling a youth bow for the fist time this week and something in the wood stove popped, made my knees buckle.

Sure am glad your eyes were not scathed in the explosion.lol

eric : the cyanocrylite does break incandescent bulbs. i forget if the fumes actually make the glass contract , or if they cause a kind of literal combustion.


i have seen bulbs break a lot working on cars , a lot of time when working with adhesives.

Wow that's a weird one

i been looking around ,and i cant find it , but there used to be some info on why incandescent bulbs break around superglue fumes. it has something to do with the glue fumes atatching to the bulb glass , then bruning and causing a hot spot. similar to what happens with headlight bulbs if you touch them.

i dont recall if the glue actually contracts or not , but the forensics teams love cyano fumes for latent prints. all you need is humidity and heat , and the fumes will build up.

you may have had a print on the bulb , and caused a hotspot.


sounds like they need to bring back mr wizard...

Wow, that's a new one on me.
Thanks for sharing, I'll put that on my list of things not to do.

A Large construction company I worked for put new windshields in about 50 trucke before sending them to Auction. The new windshields needed the mirror clip stuck on, so the shop used super glue. Every one cracked at the mirror clip within days.

WOW.............

I used Superglue on my mirror and it just fell off after a few days. Bit the bullet and bought the right (expensive) stuff made for mirrors and it stayed on.

Im making me a sign to remind me as I use super glue on lots of stuff!

Another fun experiment with CA...  In our crime lab we "super glue" items that need to be fingerprinted in order to preserve the prints on the item.  We use an enclosed plexi-glass cabinet to put the item in then put a small (about silver dollar size) aluminum tray with a coiled pipe cleaner (kids craft style) in it.  Put several drops of CA over the pipe cleaner then close the door.  

The CA reacts with the pipe cleaner and goes airborne which coats everything inside the cabinet with vaporized CA.  Let it dry for a few minutes and the prints can't be wiped off.  

Not sure if there are any other real world applications, but kind of a fun experiment.
