If you want to play around with old school “just nichrome wire” igniters, you can get a big old spool of the stuff on Amazon for less than $10:

The 28 gauge or 32 gauge stuff should work. You can try both.
The classic method is to cut off an appropriate length of the wire and then make a tiny loop in the middle of the wire using the tip of a pencil.
Insert the loop into the rocket engine as far as it will go.
Put a “spitball” sized wad of recovery wadding into the engine nozzle and push that in as far as it will go.
Finally, cover the nozzle of the engine with a piece of masking tape to hold everything in place.
Use a battery with lots of current such as a 12 volt lantern battery or sealed lead acid battery.
Now you are launching like the rocketeers of old!
See the ancient Estes Technical Report 6 (TR6) for instructions on how to make the DIY igniter out of nichrome wire.
