"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
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.
