No flame wars from me... was that pun intentional? :-)<br><br>Ok, I plead ignorance... at least to us non-chemists, " ("jellied") gasoline" (from your description of napalm) sounds a great deal like "petroleum jelly" (Vaseline)... <br><br> …but I haven't tried defoliating the back yard with the stuff... yet... so maybe not.<br><br>I only intended to inject a note of caution into a discussion on heat-sealing improvised containers of what is presumably pretty flammable stuff... that is what we want it for, because it’s flammable, yes? Personally, I'd be really hesitant to use a soldering iron- aside from any possible risk, I think it would just melt the straw too quickly to control. I might point out that it's just possible that the ignition temperature of the polystyrene straw is lower than that of the Vaseline itself, but the results of reaching either would probably be pretty indistinguishable.<br><br>Two trivia items this brings to mind: <br><br>I once met a guy who, with what seemed to amount to glass-blowing techniques, could use a plastic straw and a candle to produce tiny pitchers, cups and saucers.. pretty impressive, at least in person. He used the thicker, striped straws, not the very thin transparent ones used in fast food joints today.<br><br>The difference in pronunciation between "baseline" and "Vaseline" is a good test to see whether you're dealing with rule-based or dictionary-based text-to-speech conversion. They only differ in the initial letter, and rules for “b” and “v” are almost identical, so if the software pronounces them both correctly, it's almost certainly dictionary-based. That's pretty symptomatic of the reasons why, along with increased storage and processor power that favors look-ups, rule-based is rapidly fading away these days.<br><br>So, it’s useless… hence the name "trivia". :-)<br>
