Is it safe to use Cyanoacrylate glue for a kno3 al s salute? How sensitive is this type of flash?
Is mixing Cyanoacrylate glue with 53% KNO3, 33% Al and 14% S flash powder dangerous?
If one were to make a 3d printed salute case with screw caps and some of that powder gets caught in the screwing, would it go off?

soaking cyanoacrylate glue into any substance generates quite a bit of heat, so certainly something to be aware of. I have had a small bit of paper i
used to wipe an excess off a piece ignite by itself in the bin.
Surely its worth experimenting with 100-200mg amounts of the flash mix and putting different amounts of cyanoacrylate into it to see if there is a
danger to a potential chemical reaction between the glue and the mixture

What about the screw friction? Is it safe?

If you are not sure you should not be doing it (at scale anyway). If you are inexperienced you need to start small, and do all kinds of small scale
tests with the stuff youre using to understand how it behaves.
Ill add that KNO3 flashes are more friction sensitive than perc based ones. Friction from a screw is def a problem.

Why not just apply a bit of water the threads, to dissolve the KNO3, making it no longer explosive? If you don't intend to ever open the lid again, I
don't see a reason it wouldn't work.
Nuclear physics is neat. It's a shame it's so regulated...
Now that I think about it, that's probably a good thing. Still annoying though.

I've never done "salutes" I don't know the properties of this mixture, but 3D printing seems like a lot of work for something that's meant to break
apart on its first use.
I now have a YouTube channel. So far just electronics and basic High Voltage experimentation, but I'll hopefully have some chemistry videos soon. |

The screws have a 0.2mm tolerance and are made out of plastic. They arent too tight. Is it safe to put the powder in, put the plastic screw half way
in, add a drop of glue and screw all the way? All the contraption is plastic, no metal.
