    Acetylene is meta stable, that is it takes a outside destabilizing
    force to cause it to react. This is caused by the 3 Carbon to Carbon
    bonds which are in a bind. H-C (three bent bonds) C-H . This energy
    is stored like a bent spring. When Acetylene is burned, either with
    Oxygen or Air, more energy is released than by the simple combustion
    of the same number of Carbon and Hydrogen atoms . This makes the
    temperature of combustion higher and hotter. So Acetylene is a very
    efficient fuel. 

    A test for the presence of Acetylene gas is to make Silver
    Acetylede. Funny looking stuff, an orange flocculant (curdled ) .
    This is its only use as it is so unstable , a mouse's footstep will
    set off when dry. - From my Organic Chemistry days . 

    Why use the stuff - For 30 yrs I used it safely with no injury
    because I followed the safety rules,  and it was the best choice for
    the tasks at hand ( Oxy Acetylene cutting and welding ).  Now days I
    keep it for my Air Acetylene torch. I also still use it with Oxy
    Acetylene for cutting and welding ferrous metals. I use Oxy Propane
    for most all jewelry work besides silver. 

    Spend more time practicing safe driving - You will be safer.
