    chopsticks: good

    meh.... I made a knex rod shooter with only 3 parts. 2 knex ball halfs and a thick stubby rubber band. It could e-z-lee go threw a thick water bottle if the rod was sharpened. But no its on my roof... You can also use a wheel and a shorts stubby rubber band to get the same effect.

    Worse, no trigger at all lol.

    but its still not a block trigger but then again, what could be worse than a block trigger? nothing is worse than a block trigger

    This gun is just a bunch of connectors on 2 rods... Worse than a block trigger.

    but you don't see many like this on instructables, mostly block trigger/killerk ripoffs/ micro knex guns made of like 3 pieces that shoot a few inches

    i just think this whole topic is funny

    The ONLY thing worse than a block trigger K'nex gun is a K'nex gun that doesn't shoot at all! Sadly, I've made a few nonshooters myself :( (Mostly failed guns, lol)

    This is almost as awesome as knex furnace tongs. -

    wow. Knex guns are devolving! Nooooooooo

    Hahahaha, the amount of negative comments there will be makes me laugh! also learn to use the reply button

    u thought it would be?!? LOL
