Bob et al,
    In my mis-spent youth I was involved with many projects that required a 
squib, that is, an electrical igniter  After a lot of trial and error we 
settled on some very thin steel wire. Basically, we found some picture 
hanging wire and discovered it was seven-stranded. Unwinding one of the 
strands gave us a single thin steel wire that was perfect for our projects. 
It would instantly explode with 120 volts applied and glow brightly at 12 
volts before oxidizing and disintegrating.

73,
Al, k9si
