    How about a shot from the side ?

    this is the ''BEST'' pointless ball machine ''EVER''.

    it has one element, witch is the track

    just made it. I love it though it is useless.

    took the words strait off of my keyboard

    This thing was amazing, yet so simple.

    Where do you get the red gears?

    My motor dose not work, it is the one like yours, but older.

    were do you get motors like that!!!!!!!!!!11?!?!?

    In the old sets, when they came out.

    on this the speed of the motor is critical to making it work(less speed = less kick to the ball making it launch forward). try changing the batteries in it.

    okay, but I did have to rewire and re solder it, as the wires broke, so ill try that

    You should try taking out the two outside(the ones in between the top and bottom) gears. I haven't made it myself, but it looks like it would still work. (P.S. you would also have to take out some of the chainlinks)

    hey, i tried to make this and it just doesn't have enough information.

    you have not even heard of POINTLESS until you have seen my parent's efforts to clean my room!

    seriously: it makes the average landfill look clean.
