    Anyone who has worked in a refinery would have seen a safety demonstration of a high static charge set up in petroleum liquid just by pumping into a container.Fuel sold has a static dispersant added to eliminate static buildup.....The static charge needs to reach a certain energy level before it will ignite vapors or gases or dusts.Some very low,like acetylene oxygen mixes,some quite high hydrocarbon air mixes.Blackpowder will have a certain energy threshhold,a spark with higher energy will ignite.....And according to Davis,blackpowder does ignite by a blow,and gives tables of tests of explosive initiation energies."Chemistry of Powder and Explosives " T Davis.

    What i find very interesting ( being an arm chair delver in human behaviour) is the ability of any of us to take offense to a word or phrase written or spoken that inspires a rush of heat in our mind that turns into anger without any seemingly "just cause".

    This thread is prime example of a near miss of the above statement.

    The word CHICKEN is thought of by many as a derogative term and by a few as just an example of being skittage of an action or phrase.

    The term " being CHICKEN" takes me ... for example ... back to being taunted into doing something that will either injure me or cause mega trouble to be visited on my freedom or the seat of my britch's.

    Therefore the above phrase " if you are still CHICKEN " refers to a fear of bodily harm and not a direct inference that your masculinity is in danger of being brought into dispute.

    Interesting how these things get sometimes fluffed into an explosive exchange with just the slightest amount of spark in the brain to react to stimulation inside our brain as we react to childhood challenges that we bring crashing forward into adult life reactions.

    OH YEA

    And i use all plastic measures with all powders to include black with nary a thought of problems. I buy my powder in PLASTIC containers and think nothing of it. Seems like this comes and goes from time to time with the same old answers and questions ... so goes life and the circles it seems to travel in.

    WHEWWW!
    WHEN ALL IS SAID AND DONE...MORE WILL BE SAID THEN DONE

    hmmm
    "if you are still chicken" says to me ---so you are so scared of something that ..I.. know for sure will do ..you.. no harm whatsoever that you take these foolish extra precautions wasting time and energy in stupid safety measures . ....

    Havent heard the term "chicken" since i was at primary school 60 years ago.....generally just before you did something like jumping off the roof,or riding your bike down "dead mans hill".
