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

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
