so this one is beating me,
how do you make a very snappy e-match, see below
i believe it s lead free

It might be a dragon egg comp. That of course is just a guess.

yea, i'm trying that idea but it does'nt look promising

What about a magnesium based comp. It reacts very quickly and snappy when combined with an certain oxidizer almost like a vitamin F mixture.

it looks like its a commercial product they are selling,
i'm gonna guess it might be a nano thermite, something like
nano aluminium and nano molybdenum trioxide, or even copper oxide

Given the color of the smoke released I think we can rule out copper oxides. I would try a nichrome bridge wire with dipped in a mixture of KCIO4 and magnalum bound with NC lacquer you would need to be very careful while mixing this as it is a form of flash that is quite sensitive. There is also a potassium chlorate and antimony trisulphide mix you could give a go in a 50/50 mix and coat with epoxy or NC lacquer but again mix in very small quanities with all the precautions for the most sensitive flash and place it on a bridge wire.You could also try a sparkler comp on a piece of bridge wire but you would need to speed up the comp a little to make it faster. Or you could look up the patent to find the actual ingredients and then work out the exact mixture yourself. Outside of this I am out of ideas. Good luck with it.

Yes this works, but it is not what is being used.

i dont think so, it would be too sensitive to ship.
xmas crackers dont use armstrongs, they use a VERY small amount of silver fulminate.

A small rolled tube wrapped in holiday wrapping (think toilet paper tube). The two end slide the wrapping off in opposite direction with a small snapper charge that pops-crackles. Inside are small toys or gifts for the receiver of the cracker.

my money is on nano aluminium and nano copper oxide

might I suggest you look at US Patent US 3793100A, especially example 1
You can use KClO3 for even more energetic reaction.
Posted 02 January 2020 - 01:03 PM
i am aware of that patent
...................my money is still on a nano thermite type composition.
