This is a WARNING. Do NOT under ANY CIRCUMSTANCES point this at anybody or any living creature. It's a very strong little pen shooter, and can leave more than a mark. I am not going to held accountable for your actions, so if you are not mature enough to handle this carefully... turn away NOW.

Now for the good stuff :)

This is a fun and easy (and cheap) little toy that I invented the other day. It's very strong and shoots very far.

What you'll need:

1 Office Depot Ballpoint pen - very cheap -- 1 dozen for $0.89
(this might work with other pens, but I haven't tried)

1 Rubber band of medium length

Some String


Step 1: Making the Barrel

Pull the writing end and the little plug on the back of the pen off.
This is a very easy step, if you can't figure it out, you LOSE. Please try again.
 Hmm, step 3 in the last sentence, I'll just give you people an optional thing there for permanence, and it is only recommended if you are using a fairly thick rubber band, just a bit thicker than the one in the images. When you're done tying the string there, just squirt a little bit of glue in there and let it soak in there. Let it dry, and it is really strong. Remember. It's only optional. 
<p>there is a cuss word in the name!!!!!!</p>
<p>made a pen gun similar to this but takes less steps and is way stronger</p>
I've spent ages messing around with these over the years and for the most powerful shooter use the 'barrel' from the crayola twisty crayon things. You'll notice the improvement! :)
Thanks for this now i can finally get that annoying cat down the street <br>
wait is this cat out to get you?
you mean kill it or just hurt it
nope not getting a ink cartridge in my thumb nope
the cat down the street is doomed
<p><strong>My <br /> God...<br /> <br /> this is ment to be a fun class wepon thingy,<br /> You guys are all thinking like your planing to break out of </strong><strong>jail!!!</strong></p>
Its really good though
says the guy with shanks as his picture

I know right?
Says the man with custom-built knifes as his avatar...
maybe we are<br />
lol jk<br />
This design works at least as well and has the advantage of not requiring string. <a href="http://www.instructables.com/id/Pen-Shooter-using-ONLY-a-pen-and-a-rubber-band/">http://www.instructables.com/id/Pen-Shooter-using-ONLY-a-pen-and-a-rubber-band/</a>
im a hero. i shot this at a teacher &quot;accidentaly&quot; and i missed, and instead broke the mirror for the overhead (aka lightbox) and my teacher freaked out and quit!!!
if you think this is cool come check out my 3ft long version. i have one picture of it&nbsp; on profile and the 1/2in dowels it shoots really pack a punch.<br />
Thats wut she said<br>
Look's deadly, you could probably hunt birds with it.
that is pretty ausum :D
Can you hunt birds with it?
&nbsp;I made one of these a few years ago at work on my break in the stock room, and instead of using the ink part of the pen, I used a small metal rod that broke off one of the metal baskets. &nbsp;I launched it nearly about 30 feet through the stock room and the rod went straight through a box and out the other side. &nbsp;I decided to throw it away after that hahaha
its dangerous thats why????
man this thing could seriously puncture a trachea or two
i have a similar one but all mine is is a the body of a pen with a balloon or you could use an elastic band on the end and you simply put the pen ink thing in pull it back and fire how bout you try great fun and will be great humour at a party as it does not hurt one bit :D
interesting !!
it hurts<br>
A short,thick rubberband i found has shot the hardest,so if this design works with a small one and is powerful,try a thick one.
this is a simple yet effective design... so i took it made it double barreled and made some other modificatiions
or you can use those super small rubber bands from braces.
You hardly invented this, these have been around for ever...
I made one of the pen shooters and it works but you need to make a video because it took me a while to figure it out and when I did it went about 20.
i made one in class and my teacher took it up and he kinda looked down da barrel and it got within half an inch of his eye it left an embarassing welt and i got 3 detentions for bringing a potential weapon to class.
why would a teacher (who is supposed to be "smarter") Look down the barrel of a gun??? thats just stupid.
<p>That is so stereotypical.<br /> <br /> <br /> <br /> BTW &quot;Wait, Mr. Thompson, that thing is dangerous. Especially the end with the hole.&quot;<br /> <br /> <br /> P.S. Don't &quot;That's what she said&quot; me. &gt;:D</p>
lo, that is the name of the principal at my elementary school!<br />
like ur avatar
thx its ratchet and clank I love it
&nbsp;thats what she said
Yes but it is true, except in a few instances such my friend is smarter than the science teacher herself.<br />
he didnt know wat it was.
and I dont remember making that comment up there.... hmm....
