Ze Dragon had a method that sounded quite plausable - posted under the topic of "So, what do y'all shoot?" Maybe we could move it over here.
I can laugh now at it, but there are things like that which caused me to wonder (for several years) if I'd ever live to see 21. Just lucky I never got into motorcycles I guess.
Seems to me that dynomite fuse had several strands of cotton strands mixed in with the powder trail that influenced the rate of burning. The current cannon fuse is so small I've never taken any apart to see just how it's constructed.
