Could this Oxidiser be used?

could i use ammonium nitrate for making a fuse. by combing the powder with glue and the on the string? Thanks!

not sure, only one way to find out...
it keeps ok, you can always heat it gently to remove water, keeping it in an airtight container with some silical packages seems sensible... I used Ziploks, now I wish I still had some, though in rooting through my room I found a big bag of magnesium ribbon...
Oh I was talking rubbish about mcgyver... However the water based glue may work, dry it in the sun, the oven may be a bit hot for the glue... Another option would be to make a paste of AN and glue in a jar, push a bunch of string in, allow to sit and then pull it through a hole in the lid for a nice even and reliable burn rate...

PVA is general "white" glue (such as wood glue). It's water-based, which should make it easier to mix in the AN.

I think
Wood glue will work just fine, it's usually just a stronger PVA based glue...
Actually, you know those solvent-based glues? You can draw a line on the ground with a tube of those, light one end and get a pretty blue flame racing along the glue. I imagine that would make a Mcgyver (Magyver? McGyver?) -worthy fuse at any rate.
Hmm then again so would water... Tippex works in a similar fashion, the best thing I can think of is a simple wick fuse, make one with candle wax or possibly lighter fuel, you can use a synthetic fuse too since it's not too important if it destroys itself, the petrol one would be dipsensed from a jar with fuel in it and a wick hole in the top, this would also double as a handy lantern for when Mcgyver's burning water dries up...

So slow (and correspondingly "mild") that it will fail to reliably burn through any sort of constriction, leaving you with the most dangerous sort of fuse possible. ("did it go out? I can't tell!")
Budding pyro experimenters should buy real "visco" fuse, or use electrical ignition. IMO.

I agree....I have experience with a homemade fuse made of KNO3 and charcoal that was nearly fatal. I don't recommend this either if it can be avoided (unless you can provide stringent controls over how it is made)
thats definitely the most dangerous situation, tying with unexploded projectiles falling back down.
