Introduction: Cheap, Easy Nichrome Wire Igniters

the simple way to make nichrome wire ignitors (like the ones that come with model rocket engines) for setting off fireworks and stuff.
can be used with model rocket launchers, or cool people will make tetranitrates' awesome detonator

(C:\Documents and Settings\Matthew\My Documents\My Pictures\2007-08-25)

and use that.

I use it to blow up fruit. (Mainly rock-hard pears from my neighbors tree) You are responsible if you use it on something else. like relatives.

Step 1: Get Your Materials

to make these, you will need:

low-resistance material. (it means wire, dumbbell) I used rosin-core solder. because it was in sight and didn't move faster than me.

masking tape. (any kind of tape will work, but masking is easy to rip with your fingers)

nichrome wire. Can be bought in 10-foot rolls at unitednuclear.com, but I recommend looking for a spool of it on the internet (I used guage 38)

wire cutters and needlenose pliers help

Step 2: Cut, Wrap and Bend

to start, you need a surefire way to have the nichrome always connected to the wire. cut two pieces of wire around an inch long each,according to preference. then I suggest using needlenose pliers to wrap the nichrome around the end of it 2-3 times, using the needlenose pliers to bend the top over and squeeze it tight

Step 3: Cut, Wrap and Bend Episode 2

with about a centimeter of nichrome in between (more or less to taste) attach a second wire to the nichrome like the first and put them in the sticky side of a strip of masking tape

Step 4: The Finished Product!

all that's left is to cover it up with another strip of masking tape. when electricity is run through the nichrome, it will get hot and set stuff on fire! Yaaaaaay!

Aw man i looked at all the empty boxes!!!!!

author
diy_bloke (author)Aron3132012-03-08

That is not as stupid as it may look, for some reason instructables sometimes places the boxes wrong. The stupid thing actually is someone taking time to add these boxes

Haha true!

Florist use thin wire to make bouquets that stick out these green foam blocks. That works great too

author
whiskymonster (author)2011-10-20

i always used a single strand of copper wire, and wrap it round a match head.
a little bit of clingfilm, and dip in candlewax and they work underwater too!

where do i get nichrome?as a 13 year old would it b hard for me to get witout an adult?

author

i tink anyone can get nichrome...go to radioshack or take apart some lightbulbs....or sumtin

author

The filaments in lightbulbs are not nichrome they are tungsten.

author

I think you can get it out of Hairdryers

jeymeowmix (author)andreasawsome2008-11-22

my dads convinced that if we buy online the fbi will come :P

author
goeon (author)jeymeowmix2008-12-02

break a working lightbulb and use the filiment

author
lasermaster3531 (author)goeon2009-01-19

that's not very economical. it's tungsten and it's very fragile.

author
goeon (author)lasermaster35312009-01-19

yeah

author

try picture hanging wire. it looks like a tiny cable. pull the wires apart so you have a single wire. the wires are steel and they have a nickel or zinc coating. use something like a drill battery to ignite it. you can get 10 ft or more in i package for very little money. it's not commonly known that it works like this, so you don't need to be OLD!

I'm 13, and I'm gonna get my mom to get some on ebay. it's like 3 bucks for a 30-ft. spool of 33-guage.(too many threes...)

author
Mattrox (author)jeffconnelly2008-06-10

you can get it out of hair dryers i think toaster and kettles too

author

oh yeah, and just tell them it's a superconductor...heh, heh, heh...

toasters are the bomb for nichrome wire. can't wait till fourth of july. mad explosions

author
blackman05 (author)2010-06-04

can i use normal wires?i need it to at least catch flames for my bom to work

author
that one guy (author)blackman052010-06-04

Normal wires are designed to not heat up when current is run through- they have little resistance. Any wire will heat up when current is run through it, but the less resistance the wires have, the less heat. If you had a car battery or something the wires would probably heat up enough.

i slapped myself about 20 times during this ible

Derin (author)Derin2008-07-22

because I have the habit of looking at every single note

author
jackh94 (author)Derin2010-05-08

 I saw the empty boxes and thought no! don't look at it! but I was too tempted...

author
danm95 (author)Derin2010-03-15

I looked at the same box TWICE because the picture is there twice.

hey would you be able to use a nickel wound guitar string with a .009 gauge? for instance because I live in Australia and I am not able to get nichrome wire thanks

author
Archive555 (author)beazll092009-09-27

I live in australia, and I can tell you, Nichrome wire is EVERYWHERE! Go to garage sales, and look for toasters and hairdryers. They contain LOTS of it. Also, Jaycar in australia stocks it, it's about $3AUD for a roll.

author
killa696 (author)Archive5552010-02-06

I got some from jaycar, but it's better to just get an old toaster if possible, because it was 4.50 for a small roll where i got it.

author
coreyt (author)beazll092009-07-06

you can just buy the rocket ignitors from the hobbyman in dandenong look on there website for an adress

author
pyroten (author)beazll092009-06-16

oh yea, i recently found out thru wondering thru dse, they have it as resistance wire.

author
lasermaster3531 (author)beazll092009-01-19

.009 gauge is bad. the bigger the number thinner the wire.try thirty.

Buy some picture hanging wire. It is like twisted thin wires used to ... hang pictures. When you separate the thin wires, a simple 9v battery will make it glow hot red, and I've used it to burn fuses on my fireworks.

author
goeon (author)beazll092008-07-28

if you need nichrome wire take appart an old toaster

that one guy (author)beazll092008-07-27

you're gonna have to try that one out yourself. it may work, but you may want to try higher current/voltage if it doesn't work at first.

Can I just use some simple steel wool? Nichrome Wire is too expensive lol. I has it but it is for rocket ignitors...
