Introduction: How to Make a Fuse.

This is an easy fuse to make. It burns really slow, like 5mm per sec.

Step 1: Stuff You Need.

To make this you need:
Potassium nitrate (can be made explain later)
Potassium clorate (can be made explain later)
Powdered coal ( Can be made by crushing coal)
Sugar
water
contaner
sring

sorry no pic for this step.

Step 2: Making the Liquid

Follow this recipe
Potassium Chlorate 33 parts, Potassium Nitrate 33 parts, Sugar 24 parts, Powdered Coal 10 parts.

Make sure the coal is fine enough to go though a seive. mix it all together in a glass or beaker or a container. slowly add water until you have a thick liquid.

Step 3: Coat the String.

The title says it all. get the sring and heavly coat the string then wipe off excess with fingers.

Step 4: Make the Stuff! (optional).

To make potassium nitrate add methanol to ammonium nitrate
(fertilizer) to make nitric acid and add anything with potassium in it.
to make potassium clorate go to rotteneggs.com it is to long to write.

Step 5: WARNINGS!

Ok I forgot to put this in before.
If you don't put enough water in the compund will turn into a stiff putty and dry. If that happens it is supposed to explode. I am not responsible for any injurys/deaths caused by misuse not following instructions or anything else.

I got this from a different site but their instuctions say how to make an explosive not a fuse. I don't know weather it will explode if it drys or not.

    Potassium Perchlorate is a safer alternative to Potassium chlorate, it makes a more stable mixture. Regardless, this combination of chemicals should be handled with great care.

    i made a fuse easyer with just string PN, sugar and water! :D

    Hi to everyone. I'm sorry about the lack of detail and background chemistry. when i wrote this instructable i was still at high school and i was young and naive. all i wanted to do was write something and share what i did as i had been reading great instuctables and frankly i was a bit jealous. Anyway i am at university now and i realize that this is quite an amateur instructable with lots of useless information and potential dangerous so i apologize and the next time i write an instuctable it will be researched and backed up with fact so that there is no risk of anyone coping me and getting hurt.

    once again sorry for the bad post

    If you use only potassium chlorate or only potassium nitrate with just the sugar and some hot water it will only burn at approx. 3.5 inches per minute depending on how you mix it.
    recommended mix is:
    1 part potassium chlorate
    1 part granulated table sugar by weight
    then 2 parts hot water.
    should come out to a thickish paste like elmers glue

    Isn't it easier to just take a string and rub wet sparkler powder on it

    hmm well this is quite a silly way to make a fuse. considering mixing potassium chlorate and charcoal = H3 which is highly explosive..i suggest just making black match but if you are willing to risk making an explosive..lol well hell, go for your life :)

    It can't explode spontaneously. KClO3 (potassium chlorate [spelling!]) in a mixture of some form of carbon is known as H3 and is only sensitive. Being that you add KNO3 (potassium nitrate), there is added oxygen for combustion with the sensitivity of KClO3. This is a horrible idea. Please don't post something like this again. Just mixing methanol with ammonium nitrate (WON'T make Nitric Acid; if you think otherwise, try to make an equation!) is a bad idea because mixing chemicals without knowing chemistry or anything about what could happen is stupid enough. I'm sorry to get on your case brookech but if you can't: A) Throughly explain such instructions; B) explain backgrounds of the chemistry, then you would be better off just not putting up an instructable like so. Thank you, Brent

    I agree with cobrasniper, AN + Metho does not make nitric acid!
    CH3OH (methanol) + NH4NO3 (Ammonium Nitrate) =
    Little or not reaction, methanol is stable and AN decomposes...
    Can anyone find the reaction?

    the best fuse is just unroll a cotton ball and twist it real thin then light it.

    it wont explode in the sense your thinking. it will just poof like a small pile of gun powder. theres no pressure build up therefore there cant be a harmful explosion. unless of course you put your face directly over the compound while its rapidly burning ("exploding")

    to get an explosion u nead a sealed container and it probably wouldent spontaniously combust inless it was out in the sun

    It just said it would explode on the site. just a warning cause I didn't know whether it would or not.

    Umm, adding methanol to ammonium nitrate is just going to give you nasty gunk . You need concentrated sulfuric acid. I was gonna add how, but then realized, oh crap, 90% of people trying to do that would kill themselves because it involves lots of toxic gas and acid spatter. If you really want to, look it up on the internet. lawl methanol....who comes up with this stuff?

    I'm not saying it to anyone in particular just anyone who might try it. No point in wasting methanol and/or NH4NO3 and time.

    sorry I thought you were talking to someone else. I just found how to make it on some site because I used the real potassium nitrate.

    your fuse seems like it would work very effectively, it uses too many things in my opinion though, could make a good fuse with half that stuff
