If you saw those paper match rockets I first saw back in the 60's...I used some small wire to ignlte them.

Hah!  In junior high or early high school I figured out that a 30-gauge wire-wrap wire made a better igniter for my Century rocket engines than the expensive igniter wires they sold...  Saved money -and- made every launch successful.  I also wired my launcher to the family's car battery instead (launched from the driveway), which also increases reliability.

I claim to know nothing about blowing up resistors on purpose...   Really.
