    that is Dutch
    You're little black bat thing visitors forget step 2 BUT for the rest cool hearing


    I modified this a LOT and now it works brilliantly; it has loads of power and is very sturdy. Initially I changed it because I didn't understand how to load it, so I changed the way It loads. When I had done that it kept exploding under the pressure of the rubber bands, so I made It more sturdy. Thanks for the initial base trap though! =D

    cool contraption it works awesome!!!!!!!!!!!!!!!!!!!!!!

    I respect y'all and everything, but, this is one of the most error filled knex creations I have built. I don't mean to sound rude, but it had so many problems it isn't funny. I built it identical to the way you did but when I attempted to stretch the elastics across the trap it literally just exploded, it flew apart in every direction. It could have worked if you had made the frame sturdier. When I was finally able to put the elastics onto the trap, it snapped shut even if I held it open. The elastics also snapped. The trap without elastics would collapse if I moved it. I am ranting on but everything mentioned above could possibly become fatal if not corrected.

    Y'all represented with the bear trap which is flawless, 5.0/5.0. However this is too far.

    My rating -------------------> 1.5/5.0

    I added another trap on the others side so it kinda of workked like a bear trap but it was too much of a fail. Possibly find a way to and more strength to it because when it releises it goes pretty slow =D

    I will work on it!!!

    maybe if you like it I can work on a bear trap.
    If you want so just say it. XD

    Sure a bear trap would be cool ive looked them up on here but i dont have that many bendy sticks so i couldn't build it

    I am gonna work at it

    (with less bendy sticks)

    oh and have you ever tried making the guns? i've made a few (most fails) but kinda good so i guess you're smarter then me at this so....yah!XD

    spank you very much!!!!!

    What a lovely Knex death trap you have there.

    really cool I like it. It's a little weak or maybe its just mine but nice creation!!!

    The trap looks rally good, but you need to fix up your grammer.
