    Let your cd wheels set so the glue can dry the cd's with your pen body attached will serve as your axel and wheels for the mousetrap car

    Step 12

    The black portion in my axel you see is composed of two ink cartridges from two pens placed one with in the other from one pen ink cartridge tip to to end of the other ink cartridge body

    Step 13

    Now you can begin working on the body 1) take your 3 paint mixing steps and align two of them with your wheels these two sticks will function as the side of your mouse trap vehicle

    Step 14

    You want to allow room between the side of the vehicle and your wheels so they don't have friction against the body while in motion, do this with both sets of wheels

    Step 15

    After you have made sure there is room between the wheels , leave the wheels between the side body and with the ink cartridge axel inside the wheel glue that part down to the cars body

    Step 16

    Step 17

    Step 18

    Now take your third piece of wood ,cut it so it can fit across the body of the car you will need to glue it down and tape it if you like, lastly once the glue is dry, then glue your mousetrap on top

    Step 26

    The part that you just straightened will function as the hook of the hanger connecting the fishing line to the lever arm
