Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

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)

Step 2: If Using Rocket Enging...

first get the rocket engine, an a or b size will do, if you are not over 18 this could be a problem but they are easy to get. just go to a hobby store, what the rocket engine will do to the fuse is increase the flame an give off puffs of explosion.

Ok so get your engine, lay it on a big piece of paper on concrete or a hard surface. lay it on its side, gently tap the side that is up with a hammer starting at one end. you should see the cement or black charge braking apart. continue breaking util the tube is empty.
break the pieces you have now until they are close to a fine powder. be careful

sorry no pics of this yet possibly another instructable

Step 3: Lay Out Your Fuse and Unwind

tape one endn of your yard to a table. put a piece of paper unter it and tape the other side down. WAIT! before you tape the second end, untwist the yarn so it is less tightly twisted.this will help it retain more of the rocket engine or nail polish.

Step 4: Using Nail Polish and Rocket Engine

Lightly paint the yarn all over with the nail polish, i have found that colored polish works better. when you have a good coating, spinklke the wet polish with the rocket engine. make sure most of it sticks. the paper underneath catches excess engine to be used again.

Step 5: Let It Dry!

It should only take a couple minutes to dry and then YOU'RE FINISHED!!!

Step 6: Alternate Methods

1) coating just yarn in alchohol will work as a fuse, but you have to use it before the alchohol dries. the yarn it self will work but only moderately.
2)you can roll the yarn in just engine and it will work somewhat better than just yarn.
3) just polish

Step 7: Time to Light!

Using an ordinary lighter you can light the fuse.

1) the first pic is with clear with engine
2) the second pic is with colored with engine.

Last not , be careful there is serious flare and danger to these,USE COMMON SENSE and HAVE FUN!!!

    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.

    I make my fuses this way -

    100x's cheaper and much more effective.

    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.

    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.

    I am thinking of using thinning nail polish with the flammable liquid and soak the string in it and let it dry
    I tried making some fuse with twine soaked in acetone.
    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

    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

    please email me if you succeed. 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 "fuse", 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.

    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!
