I made several smoke bombs using a recipe similar to this one:
However, I added both baking soda and crayons thinking I would get color
with the crayons but did not. However, compared to the standard recipe
without the crayons/ baking soda, I think I like this one better because
it burns slower and smokes more BUT it is hard to light which brings me
to my question.
For fuses, the simplest thing I've tried and works well are sparklers.
I cut about an inch off of a standard sparkler and place this into the
smoke bomb paste while it's still warm. Works ok, but cutting the
sparkler causes about half of it to break away each time. I'd like to
come up with an actual fuse if I could.
I tried making a fuse using the KNO3/ sugar recipe and some cotton
string, but it won't burn well and keeps fizzling out. Granted I made
it with a thin, almost kite string thickness so maybe it was too thin to
work well. I've since obtained some #4 cotton yarn (the thickest I
could find) and might repeat the experiment again, but I have a couple
1) Would the thicker cotton yarn burn better than the kite sting?
2) What is the long term reliability of these kinds of fuses if in
storage (for example, I may use a smoke bomb next week and then not
another for a year... would the KNO3-sugar fuse still be in good enough
3) I tried breaking up sparkler material and then spreading it onto a
toothpick that was first dipped in hot glue. It stuck well, but
performance was poor. Any better suggestion for repurposing sparkler
material into a working fuse?
