How to make an awsome fuse with easily attainable products that doesnt leave a trace and lights easily.

Step 1: Get Your Materials

To make this fuse all you need is ...
Yarn (as long as you want your fuse to be)
a rocket engine (technicly optional but is somewhat important)
rubbing alcohol ( also technicly not required)
clear nail polish ( works pretty well)or
colored nail polish( works very well)
<p>Okay, nice(ish) fuse, but to be honest it would be cheaper buying visco fuse (70metre) that breaking up an expensive a perfectly usable rocket engine. Does not make sense to me but, each to their own.</p><p>I make my fuses this way - <iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/HZbafj0s8gQ" width="500"></iframe></p><p>100x's cheaper and much more effective.</p><p>Have fun making them people, but if I were you replace the paper with a good quality felt paper, and use dextrin as a gumming agent.</p>
I tried making some fuse with twine soaked in acetone. I accidentally left the lid off the bottle of acetone, and the vapour caught and turned it into a pulse jet. This improvised jet then lit some other things on fire. I did manage to put the blaze out with a fire extinguisher, but it really made me think about how dangerous this sort of thing is. By the way, the fuse didn't work at all. The flame traveled the whole length of it in a fraction of a second.
you could use a flammable oil such as tea tree or eucalyptus oil, or Brasso or Silvo can be used, as long it is not choked or swallowed.<br> <br> I am thinking of using thinning nail polish with the flammable liquid and soak the string in it and let it dry<br> <em>I tried making some fuse with twine soaked in acetone.</em><br> Acetone is as flammable! since u said it turned into a pulse jet, I'm goint to try it!
might not wanna break it into powder with the hammer... it could very possibly explode if you hit it too hard
man up
It would only happen if a spark appeared in the hammering process.
is this blackpowder or match head?
heh When i made black powder i put it in a coffee grinder...But i grinded all ingridients seperate .....SO DONT THINK ITS SAFE TO PUT UNSTABLE EXPLOSIVE COMPOSITIONS IN A COFFEE GRINDER I DONT RECOMEND IT.
agreed, albeit unlikely. the method i use is a light tapping, far from a full swing. This technique is intended to avoid this danger. admittedly not the ideal way but the force required to spontaneously detonate is is much more than I am providing with the hammer. Cheers, Mspark400
will flash powder work?
It will be flash cord if you used that stuff!!!!!
probably, but it'd burn quite fast.
please email me if you succeed. xiaosijun@gmail.com. i am quite interested in your invention
well. i think that is not a fuse but a more flamable string. fuse has to be able to burn without oxygen. although you add some kind of powder to you &quot;fuse&quot;, and the powder may generate some extra oxygen, i recommend you put the string in sand to test if it still burns well.
Nice one! You could also clip off the heads of matches, crush them, then dissolving them with water and soaking a length of string in it. I haven't yet tried, though.<br />
use white lightning wax lubricant for bikes it doesn't dry as fast and it burns really well soak some cotton or hemp string in it and light it up!!!
The best way i have found to make a some what reliable fuse is as follows: Grant's stump remover/ potassium nitrate containing substance. Dissolve in water till saturation, soak napkin, let dry and cut off a small rectangular piece, it works great!
adding sugar with saltpeter should work better. Saltpeter as such will not be so good.
Salpetre, or Saltpeter, or Potassium Nitrate. Same things...
If you can get me any of the 3 above, im paying you a big extra. in canada.
Well I know that. I said put suger in with it. Wierd people trying to show off.
Adding sugar does nothing extra! Just makes it smoke more...
Actually, it makes it more ineffecient...
Actually, it decreases the burn rate, so the fuse burns longer, increasing the time before your explosives go off
Exactly. Why wouldnt you want ineffeciencies in your fuse? It gives you more time to run! -PKT
It does, along with creating smoke, sugar burns better than most natural fibers. The smoke mixture one sustains better.
yah well not all ppl can get those items can they... great job dude....
If you live in the USA you can.
Yes, the USA is good for being able to get pyro chemicals. This may be a bad thing, but I think it is quite nice.
just soak string in purell hand sanitizer and lite it
the problem is that as soon as the alcohol evaporates, the string will just be slightly wet and certainly burn no better than just string alone. cheers, mspark400
dip it in purell and immediately lite it
Seriously people, there is a Macro setting on your camera. It allows you to take up-close pictures without them being blurry. The most common symbol for this Macro button is a flower, more specifically a tulip. Other than that, this is a good Instructable.
I am quite familiar with the macro setting and i am a semi-pro photographer now. These pictures were taken long ago, before i learned to consider these things. Perhaps in the future i will redo this with my dslr and make it better. cheers, mspark400
i do all kinds of pyro stuff and a reliable fuse is hard to make on limited materials so i usualy just use ordanary gold sparklers, they are reliable, burn in low oxygen, are wind resistent and give you enough time to run the f**k away.
Yes, time to run is a good thing.
Common sense, is that why you lit it next to some rubbing alcohol. Other wise good work but um shouldn't it 100% cotton yarn because synthentic just melts I can't get it burn.
Last I remember, all the synthetic threads that I have burn better than cotton.
I know that is what it looks like but I'm no hypocrite. Despite appearances none of those containers have what they say, I'm pretty sure there was mostly water (don't ask me why) I do appreciate your concern for safety though so thanks for checking and yeah i didn't mention but you are right it should be all cotton yarn:)
You can't seperate alcohol from water without burning the alcohol. I don't blame them for that.
I would suggest putting a thin layer of glue so it help burn...
ahhh my hand missing a finger now thanks to you!!! jk great instructable man keep it up
I do a lot of pyro stuff and I have never been able to make a good fuse this is awsome! But does'nt the polish become pointless after it drys?
not really still flares well ps glad you like it
So, nail polish is flammable even after it is dry, correct? Or is it the fumes that are flammable?
nail polish contains polymers (plastics) and acetone. When you burn it without drying, the acetone makes it burn better, but otherwise, only the polymers will burn.
nope, still good when dry!
I recently became aware liquid glue is quite flammable... Would it be possible to use glue instead of nail polish? Will it still burn when its dried up? thnx
