    WTF? generaly means what the f*** as for BTW... well to me that's been a mystery for quite some time.

    yes i do because you have a dumb name and you cant spell stupid right

    o yea and i was ganna do a prank with my name but i didnt so thats why my name is killer k lulz

    Finally an actual torsion powered k'nex!!!

    Nice! Quite coincidentally, it looks like my catapult too! Except, I wish I came up with this idea. Not only is it more powerful (at least for me), but it is smaller. Love it.

    orange peice? dnt u mean the light gray connector but u just got som that are orange cuz i ahv som of those

    Instead of leaving the rubber bands the way they are, put the arm through the 2 of them, and twist them once or twice before putting the whole thing back, should get more power
