If not where can I buy it? Lowes? Its fror rocket ignitors.
You don't need expensive Nichrome Wire to ignite your rockets. Any fine gage wire will act like fuse and burn up if you place enough current through it. With a little experimenting you can take apart multi-strand wire like AC line cord and use a small piece of one strand maybe a half inch long as the fuse. Connect it to your power source (a battery ?) with the full AC line cord. When the power is applied the single strand will take the brunt of the current and light up like a light bulb. It will burn out but, by then your rocket will be rounding the moon. A single D cell will light up a a fine wire very quickly. You can use a couple of alligator clips to connect to the strand so you can quickly connect to your next rocket......

"Expensive" ? you can get 100ft on amazon for 7 to 11 bucks depending on the gauge you want.
7 to 11.00 bucks if it is readily available. I agree for most it would not break the bank, although you may not need it. With a little AC line cord which can be salvaged almost anywhere anytime can do the same thing with no cost out of pocket. And if your local hardware store doesn't have it you can still make your rocket fly!! Thanks for the feed back ELSergio...
from which thing we can find this wire
I agree with seandogue. Old toasters are a great source for this. Not only will you find a ton of nichrome wire in them, but you'll also find ceramic tubes used to guide the wire which can be handy for whatever project you're building.
Never seen a toaster with ceramic tubes, only mica plates to hold the wire.
Hair driers are another source, so are light bulbs (incandescent).
light bulbs don't have nichrome, they have pure tungsten filaments.
toasters have nichrome, but it's thick stuff which may be impractical for model rocket igniters
Steel wool is another source of fine wire suitable for igniters, (steel not nichrome, but it's thin stuff.
wire-wound resistors have thin nichrome wire but there's cement encapsulation, cheap soldering irons have nichrome in the heater sometimes it can easily be extracted.
Jason, not all toasters are the same (obviously). I've seen both thick and very thin nichrome wire in them. The older ones tend to have thin wire and the ceramic tubes I was talking about.
here is a company that sells nichrome wire http://www.jacobs-online.biz
try an old toaster. Lowes and Home Depot aren't going to carry it.
Also, do a quick search on the net. just type in "Nichrome wire" in the address bar of Firefox or "Find Nichrome wire" in either Firefox or IE (not sure about Apple's or Google's browsers) and several distributors/mfgs will pop up
unitednuclear.com is a good place to start for anything chemical :D
Your local hobby shop may have it.Here's a link look down at the bottom - http://burnsmodelaircraft.com/index.htmLight guage guitar strings - the high E or 1 st. string on some sets will be the right thickness and those strings are usually high nickel. You could just swipe you little brother's string to try it out.Lot of links to buy on the net if you so choose.
