Step 4: Crimping

This step is key. If the crimp is not tight enough or is not correctly done, the rocket will just burn. It may be a bit complicated but after you do one and see what I'm talking about, it should come easier. Start off by inserting your crimping spacer, feeding the fuse through the hole, until the masking tape stops it from entering any further. Next feel around for the space that is created between your spacer and the bottom of your fuses and work it around and squeeze it. You want to make it weaker than the rest of the tube so it will fold easily. Now firmly grip the top of the rocket with one hand and the spacer with the other. Slowly twist and push until the paper folds down nicely. To finish it off, tie a knot around it with your string to keep it from unfolding.

What do you think rust will do to the color?
Iron oxide should produce orange sparks trails.
Thank you!
only problem is im running out of fuse fast and im a poor man, but will give it a try someday!:)
Very good idea.
I've got some fuse, (+100) which burns REALLY fast, like 1 sec/ft fast. Will this still work? Or will it just blow up the paper casing due to the extreme pressure? Has anyone tried this with this kind of fuse?
Hrm, yeah, that may blow up. Might as well try! If it does you just have a nice firecracker.
greatness! mine do circles and i love it
Is the crimp a restricted nozzle?
Yup! It provides the directed lifting thrust needed for the rocket to launch. Once it's flying, the nozzle will burn away but the burning fuse is enough to keep it in motion.
Cool....Very Cool
thank you so much this is awesome i made one and it works awesomely and i love it
Glad to hear it!
could you use 3mm chinese visco that burns at a rate of 28second per foot
Yeah that sounds like it would work. Light a test piece and put it on a hard surface. If it starts shooting around and moving quickly then you're good to go. If it just sits there and burns without movement, it probably wont work.<br>
what kind of fuse would u recomend <br>
I just used the kind that the local firework store carried. Any type of fast burning cannon fuse should work. I don't have specific details on what type I used. It just came in a clear package labeled cannon fuse.
thanks, i just ordered some from cannonfuse.com.... Lets hope it works <br> <br>
could you make it from cannon fuse
Yeah, I believe cannon fuse is the same as visco. For a quick test, take an inch or two of your cannon fuse, lay it on the ground, and light it. If it starts spinning around and going all over the place, it should produce enough thrust to be used for these rockets.
could you also use flying fish fuse for the 1 inch pieces? i want to make these with color but i dont wanna use metals
I'm not entirely sure... I've never used any flying fish fuse so I don't know if it would work. It looks similar to visco so the thickness would be about the same but I don't know how much thrust it will put out. Give it a go! That's a good idea!
well, it said on the site that it put out a TON of thrust, so i think it should be fine, maybe even better.
K cool! Give it a go! Let me know how to works!
does anyone know wher to buy this that will ship to new zealand??
Thats A UK SITE <br>http://www.wirelessfireworks.co.uk/fuse.htm<br>AND YOU CAN GET THE CHEMICALS FROM<br>http://www.inoxia.co.uk/
I'm not allowed to buy stuff off the internet so where can I buy disco fuse in the bay are?
lol, you're not allowed? and wtf?! DISCO fuse?
Yeah I'm not allowed. My parents are really strict about what I do I proabably should find a beter hiding place for those F rocket motors in my closet. And curse the typo god about the disco.
Great idea. my parents won't let me buy fuse though, they know how much of a pyromaniac i am so they don't trust me with fire. lol, nice job though.
Haha yeah my parents weren't too thrilled with my hobby. Thanks!
how'd you get them to let you? right now i pretend i am into model rocketry so i can get rocket engines (which i crush up and make powdered fuel from). it'd be niice to come outta hiding.
Hah well it depends on your age. When I was younger I had to hide it. Later, my parents just saw that I was being responsible about it. I also assured them that I wasn't making anything destructive like m-80s. I like the display aspect of fireworks rather than the blowing stuff up. I don't know how you are.
well, i have to agree. i have to hide it all. i convinced her to buy lighter fluid by offering to cook dinner.
Haha nice.
I know right... here come the fireballs... I also convinced her to buy me lighters by saying i need them for a boy scout camping trip (to light fires) that worked too!!!
Exact same way I got my lighters
she could just be humouring you.
Ha we weren't allowed to bring lighting to our camping trips... or electronics.
i wasn't either, but i brought eight of them anyway!
Tissue paper soaked in gas
so.... your parents won't let you buy the only pyrotechnic device specifically manufactured to save people from burns/explosions/death? hm... I need to get my hands on some visco.... there's so many things to do with it, and I don't have any.
hobby shop??? they usually have fuse.
painters tape and black powder are my fuse hahahah!!!
What is the thickness in the fuse that your using? does it matter??
I believe it's just 1/8 inch fuse. Smaller or larger ones would probably work I would assume.
all right thanks a bunch :)
You know, this looks like a good idea. The only problem is that I havent been able to find fuse of any kind anywhere, and ive needed it a lot. Is this just like the standard green fuse on firecrackers? and where can you get it?<br />
