I have experiment tonignt a smoke bomb mix but I am not sure
the smoke bomb work.
the formula is:
50% finely powdered gold sparklers mix
50% sugar
or
60% finely powdered gold sparklers mix
20% finely powdered sulfur
20% finely powdered table salt (sodium chloride)

I will use sparklers mix because this mix support the combustion by a hot flame (2000°c)

jérome

dont try all of this mix if dont work
