Introduction: Simple Bic Mechanical Pencil Gun

Picture of Simple Bic Mechanical Pencil Gun

This is a very simple gun that you can make out of Bic mechanical pencils. Its a little different from
beam's mechanical pencil gun and black hole fun's. We used to make these all the time in middle school and shoot each other in class. Just thought I'd bring some old school fun back to the adult world.

Also there's one of my favorite stingers if you really want to inflict damage.

I feel I should also put a disclaimer: I'm not responsible for any damage or injury caused by this. Please do not shoot people in the face. What you do with this is on you.

Step 1: Get Things Together

Alright you'll need:

1 Bic mechanical pencil
1 rubber band, preferably smaller than the one I got.
Knife and/or scissors perhaps pliers.

Step 2: Preparing the Pencil

This entails basically just taking off the front of the pencil.

First picture is of just the cap off.
Second picture is where you need to cut to detach the inner shaft.
Third is of the two parts you'll need. There may be a fit problem so just shave things down with the knife or the scissors.

Step 3: The Making of the Pencil Gun

Now just insert the inner shaft into the outside backwards as seen in the first picture.
Then put the rubber band around the top of the clip and the eraser.

Step 4: Shoot Things!

Now you can add rubber bands to the clip and eraser if you're worried about the rubber band staying on. I personally liked the ability to just quickly take apart and put together and never had a problem with the rubber band flying off.

Hold at the top of the clip and the eraser. Insert the ammunition at the top and fire away!

Step 5: Want to Put the Hurt On?

So is that guy across the hall annoying you a lot today? Well you could go a little pointier on him. These make cross classroom shootings hurt.

What you'll need:
Small sheet of paper.
Stapler with staples.

Just go through the pictures and there will be instructions.

Do we have to use a bic brand mechanical pencil?

cody6268 (author)2014-01-26

I had to modify mine a bit. The lead tube was a little too thick, to fit in reverse as you showed, so I put it in the original way instead. It can shoot ball bearings (but airsoft pellets are too big) and matchsticks. It's pretty powerful, and can perform just as good as a low-end airsoft gun.

Great idea I can shoot bbs at my friend now with out him figuring out what happened

izzikienzle (author)2013-02-11

My reply isn't working but to the 4 officers kid, mine does too. But the kids at my school bring guns and knifes and fireworks all the time so I'm grateful. Plus, one officer is in a band (cool), and he let me ride in his cop car (cool except I had to ride in back.. So little legroom)

I need one of these. Paper wasps are nice, but horribly inaccurate.

jackojack12 (author)2011-01-28

I shot my foot! :(
But great classroom weapon! :)

samando (author)2008-06-24

I have recenntly made this gun, however, because the ramrod is sticking out slightly, you can put it up to someone's soulder and fire it! (without the ammo), using the right type of rubber band, it really hurts

Kapower (author)samando2010-12-05

nice, long range and melee, 2 in 1!

mappum (author)2009-01-10

put a little bit of duct tape around the edge of the end of the tube(on the opposite side of the barrel) and it will make it a little quieter and better for a classroom :P

Kapower (author)mappum2010-12-05

or you could use some foam that you could glue on.

AWESOME9802 (author)mappum2009-12-12

I'll try that, but won't it clog up the barrel?

bigfootduck (author)mappum2009-03-06

lol. thats true! ill have to use that in math....

deterville (author)2010-11-23

freaking awesome!

Air_Assassin (author)2010-11-22

optional:1 : use a pen barrel 2: use a copper bb 3: for the pen barrel use a plastic bb p.s. not trying to be mean just an option

Samek_1 (author)2010-11-07

MajorBromley (author)2010-09-08

rcharles (author)2010-01-22

I'm going to do this in spanish class this will be fun !!!!

striker187 (author)2010-01-22

Note to self: use EXACT same type of pencil as in pics.
I used a matic grip one and the long part wont fit down the barrel even with a lot of shaving

Dr.Squirrel (author)2009-12-27


Mr.turtle (author)2009-11-25

You can put a little cut into the top of the clip at a slanted angle so it holds the rubber band in better. Worked for me.

darktooth (author)Mr.turtle2009-12-07

Also, you can put a cut in the erasor and wedge the rubber band in it

Colonel88 (author)2009-11-19

I like the idea for the Pointy Ammo.

I did this right here in class, and got my rubber band and scissors from the teacher. This is awesome, great instructable!

11rex11 (author)2009-04-17

wow i didnt think this would work but it did!

dirtnap (author)2009-03-29

Very good weapon but i like the 1 by beam just because of the eraser part it gives it more power not much but enough to penetrate a lil more. Very good though this was my first try at this weapon when i built it my eraser broke i wasnt using thick enough rubber band. lol
