well i see that it burns just like string would if lit like that, according to what ive seen, nothing has changed about the string, how well does it burn downwards into a very confined hole only just big enough for the fuse to fit in?

oldmanbeefjerky (author)2010-11-23

i really dont see how this could possibly work, at least not like a normal fuse if it wasnt using 10 year old sparklers that still contain chlorates.
are you certain this works like a normaal fuse, that could burn through even tiny holes, that could burn even if wrapeed in tape?
also please retake those pictures, quite frankly, your better off drawing your pictures, than using those ones, every things a blur

do you think it would work with these?

goeon (author)dan.kent102009-09-10

it might but just to say match rockets really suck with fuses

This Instructable seems to pull it off:

goeon (author)dungeon runner2010-02-20

 It doesn't go that far anyways so why do you need a fuse for it 

Its not like its going to blow your face off : /

dungeon runner (author)goeon2010-02-21

It's more about aesthetics, really.  Everyone knows it's not an explosive until you add a fuse ;).

Plus, if you live in Maine where it's windy (like me), lighting one of these is a total pain. Matches blow out too easily, lighters burn your fingers, and other more dangerous options will destroy the rocket completely. Don't ask.

What do you mean by "make it mash"? Do you mean add water?

goeon (author)dungeon runner2010-02-19

 "make it into a mash", yes 

dungeon runner (author)goeon2010-02-20

Ah, thanks! Nice instructable by the way!

 I have a ton of Visco Green waterproof fuse for

goeon (author)Bromac2009-12-01

 no thanks ive already got some 

GZNG (author)2008-09-07

dude why waste materials when you can simply just put a sparkler straight in and besides sparklers can burn in low oxygen

goeon (author)GZNG2008-09-08

the metal rod is a pain

GZNG (author)goeon2008-09-12

i don't see how since the rod can be bent...

goeon (author)GZNG2008-09-15

though after you have a burning hot metal rod a pain to pick up (yes I'm too impatient to let it cool)

thermoelectric (author)goeon2008-09-22

That is what water is for :-0

goeon (author)thermoelectric2008-09-23

yeah but what happend one time is i made a super powerful firecracker and it shot the rod out

thermoelectric (author)goeon2008-09-23


awang8 (author)thermoelectric2009-01-14

Yeah! That's not a pain, that's awesome!

thermoelectric (author)awang82009-01-15


goeon (author)thermoelectric2009-07-18

when it almost shoots youre uncle... thats no awsome

thermoelectric (author)goeon2009-07-18


kibbler (author)GZNG2009-02-16

The powder comes off and it can jump the fuse, as the burn on my thigh shows.

GZNG (author)kibbler2009-02-16

then wrap it in a thin layer of tape before bending

Plasmana (author)2009-01-02

I made one of those, but it does not burn well, I find that using black powder works better.

goeon (author)Plasmana2009-01-02

worked fine for me really hard to get my hands on blacpowder

jamesjamesjames (author)goeon2009-07-12

make it :) doesnt need to be quality if its just for a fuse. just mix charcol dust with an oxidiser (e.g. pottassium nitrate) mix it up with some dextrin (or epoxy glue) and coat the string

pretty good, could do with better pictures and a bit more instruction, The video is good though

goeon (author)=SMART=2008-07-19

my camera it terible

=SMART= (author)goeon2008-07-20

oh ok, you could buy a webcam from the dollar store, that would take pictures

goeon (author)=SMART=2008-07-20

thats what im using

=SMART= (author)goeon2008-07-20

oh... well maybe buy a cheap piont-and-shot digital camera then

goeon (author)=SMART=2008-07-21

maybe i could just focus this one

Marche (author)2008-07-19

You need new pictures.

guyfrom7up (author)2008-07-19

no bad notes: needs better pictures use the instructables notes feature give a bit more info, like how to get it on the thread, what kind of thread, etc. have a little section or place that says homemade fuses are unsafe
