    they are good to shoot teachers.

    so commen
    they put things like this everywhere
    it gets lame

    flip it around and insert the pen on the closed end and it will work better

    This was friegen awesom ma friend Tokashi made iot brought it to school shot it in the seiling and he is still trying to get it out
    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    :)

    This was fun to make. I shot it into the ceiling @ school and all my friends want one. I changed the design a bit but it still works.

    how do you take a bic round stic med apartt

    TIP: you might want to tape or plug up the end that doesn't write, so if it gets lost, ink won't leak all over everything.

    WOW I WOULD HAVE NEVER COME UP WITH THIS IN MY ENTIRE LIFE!!! YOU ARE SO CREATIVE PLEASE COME UP WITH MORE THINGS THAT NOONE WILL EVER THINK OF HOW DID YOU THINK OF THIS??

    JUST A WARNING EVERYONE: If you're shooting at the ceiling, beware of sprinklers.. A guy in my grade 8 class hit one last year.. Wasn't pretty. Black liquid came out of it and the entire school was evacuated.. Just if you're aiming for a sprinkler beware of the consequences.

    I`m so glad I went to this website and found this!It`s FAST and EASY!Thanx so much.

    Very nice and easy to make :D! Tyvm :) ^.^

     that was the best pen gun ever thanks man

    btw, BBQ sticks are SUPER DUPER powerful.

    i suggest taking the finger of a rubber glove and putting it over the hole then rubber banding it so that it stays. But yours seems pretty strong O.o!

    I used a Faber Castell connect a pen though they actually textas and i used dressmaking pins + electrical tape around shish kebab skewers and it can pierce :- dry wall, cans (full+empty) and break glass. I'm also working on a flaming variety of ammo too with 2 motheds already working >:)

    awesome very very simple compared to other pen guns

    dude that thing whent flying and made a little hole in my wall

    I did this and I shot an airsoft bb at the floor and it bounced up and hit a filing cabinet during study hall. Then I threw it at my friend so I wouldn't get caught, he got caught and it was funny to see the teacher trying to ask him how he got this and why he did it and he was confused and just cried and shaked the whole time.
