    Poles is actually Rods.
    Put your finger on this bit and fire is actually a trigger

    Drive pole is actually a ram rod.

    How far does this shoot?
    I have a feeling this will shatter my K'nex rods-
    Fast-moving, plastic K'nex rod + dense, solid glass (?) marble = shattered rod?

    Cool idea though. Could you post a video?

    no can't post video no cammera and have not broke a rod yet after 500+ shoots and i live in australia and we measure in meaters not feet so i have no idear on how har it shoots and all my good rubber bands have gone missing and have not gone and got more yet

    Aussies= Australians.

    1 metre = 3 feet

    And it's spelled metre, not meter ( in Canada)

    i know about the metre, i also knew about the aussies, i just know people who think calling australians "aussies" is impolite.

    That's odd, two of my friends moved from Australia two years ago, and they call themselves aussies....

    well metric or non metric doesnt matter, google can transfer feet to meters or vice versa, it can even do hogs heads(actual unit of measure, weird, eh?) to cups!

    only if the glass is stuck in position, or the firing-pin has so many rubber-bands on it the whole gun would buckle, trust me this works.

    a good gun dosent shoot far tho 3 1/2 stars. tip: use two rubber bands

    try ing to put trigger on new gun but not haveing any luck

    a marble is a hard stone that they form into a ball and it is shiny and very smooth
