Introduction: Pencil Crossbow. DANGEROUS!

In this instructable i will show you how to make a dangerous crossbow out of:
3 pencils(unsharpened)
One Rubberband(general size, thick)
Masking Tape
Hot Glue
Ink Part of a Pen

Step 1: Glue

Take hot glue, and glue the two pencils together. glue on one side, and leave no gap between pencils!

Step 2: Glue...again

Take the third pencil, and lay it near the unsharpened part of the pencils, centered, on the glue side!

Step 3: Rubberband

Take some scissors, and cut a little groove in the eraser. Then, take a rubberband and put it in the groove. Hot glue in place.

Step 4: Other Side...

take the part of the rubberband that isnt glued, and s t r e t c h it out to the other side. glue in place

Step 5: Take the Duct Tape

just a small bit of it, and put it in the middle of the rubberband, on the side where there isnt any glue. the tape should be able to fold over the rubberband top and bottom.

Step 6: Insert the Inside of the Pen...

and fire!!!

NOTE: THIS DEVICE CAN BE DANGEROUS! DO NOT, UNDER ANY CIRCUMSTANCES, SHOOT AT SOME RANDOM GUY, EVEN IF YOU HATE HIM. ANY CLAIMS OF INJURY WILL NOT BE TAKEN INTO MY OWN HANDS.

USE AT OWN RISK!!!

 Nope, it's just a bow mounted on a stock.

bows dont use rubber bands...

Well, they're not Y-shaped either. So it's not a crossbow, not a bow, and not a slingshot. So what is it?

p.s. (lol)
sling shots dont have to be y shaped.

o and i just looked at the images on ur reply.i read the 2nd(bottom) 1 and saw that it says :"slingshot:a y-shaped stick OR PIECE OF METAL* with a piece of elastic fixed to tha top parts,..."
*...meaning that it can be either a y-shaped stick OR a different form of body(in this case a piece of metal)

 Okay, I'm gonna get my hard copy dictionary. *gets webster's dictionary* VICTORY!!! *gets camera and takes pics* you can't argue with webster. Like you said, "online resources tend to have public access where people edit the meanings" so your above reply is wrong.

i meant an at home dictionary;online recources tend to have public acces where ppl edit tha meanings into their particular view of an object/ idea ;including ppl that have no/little knowlege of that thing. im sure if u find a non public resource u will find many different views of a slingshot.

it IS a sling shot b/cause it uses a simple body to hold a rubber band/propulsion device to "whing" ammo through ur neighbors' windows>.> if u dont understand(no offence) then look up slingshot in tha dictionary...

hey. nice instructable. i love crossbows and even though the one i posted isn't the best i consider myself a crossbow judge (please let me be dilusional) i think this one is top five. sturdy cheap. nice. by the way... does anyone know where to get surgical rubber bands. the are just a strip of stretchy. but very wide, and would be great for a medium scale diy crossbow.

The pictures are a little blurry, but the last one basically sums it up. I'm going to try this for sure!

If you sharpened the pencils, you'd have a close combat weapon as well...although that would make an ignorant user more prone to hurting himself or nearby, unaware victims.

I made one with a hollow barrel like origami_king123 said, and it works good all the same

Nice idea with the supper glue. I always use some paper clips or string. You do know that this can be use for air soft, right? VERY inaccurate, but fun. I prefer to just use a few pen barrels , makes it much more accurate.

author
origami_king123 made it! (author)2009-03-15

you could take the hollow part of a pen and put it on there to make a barrel

In the last pic u had the pen tube laying on that groove in between those 2 pencils, could u use the groove on the other side and shoot under the 3rd pencil. in the little gap it might be more accurate

it is not a real crossbow since the only force it uses is the rubberband and not the pencils. It is a good idea to make in school though.

author
Ian01 made it! (author)Ian012007-07-05

Correct. Real crossbows use a flexible bow, not a stretchy bowstring.
