Mechanical Pencil Staple Shooter

This instructable will show you how to turn a cheap mechanical pencil into a staple shooter. The shooter shoots closed staples about 30 feet. It's really cheap and easy to make.

This probably won't do any damage, it's just meant to annoy people, but anyway...

Step 1: Materials

Materials you need:

-A 0.7 mm mechanical pencil (preferably with 2 prongs to push out lead.)
-scissors and or pliers
-tape (optional)

Step 2: Removing the Cap

To remove the cap, you can do 2 different things.

1. If it is a good quality pencil just screw the tip off to see the lead loader.

2. If it's a very cheap pencil, which actually work better in the end, you use the scissors to wedge the cap on the tip off.

Now you can see the lead loader. If it has 2 prongs, go to the next step, if it has 3, you need to start over with a new pencil.

Step 3: How to Load and Fire the Staples

To load and fire staples, get a stapled staple. Stick it in the lead loader by pulling back the ring that secures the lead and running a folded edge of the staple through the lead loader and have the staple run along the grooves in the lead loader.

To fire, pull back the button that you use to lengthen the lead and the ring should push the staple out propelling it toward your helpless unsuspecting target.

Step 4: Optional Stuff

To make loading easier you can tape the ring to the pencil so it does not move. It isn't as stealthy but it makes loading much easier.

You can also modify the staple using the pliers and scissors. You can cut it in half or do anything as long as it has a folded edge.

The ideal target is the hair or neck because they won't know what hit them and they might find staples in their hair later and say, "Curse you _______!"

Step 5: Feedback Please

    dude me and my friends would do this in 5th grade currently in 8th and we would also cut off the prongs and use the pencil to either launch the part that you put the led in at the ceiling or we would use just the outer part to fire spitballs at each other

    With this staple pencil Im gonna be king of the classroom!


    This is awesome! I built one, took it to school, and "attacked" friends with it. No one got hurt, thanks to the shooter not having much power.

    its not really hard. just take a regular staple and the bend the staple in half with each leg on the opposite side, make sure there is a little hole in the middle

    Here's a comment. This is a pretty cool idea. It's one of those things that doesn't seem like it should work, but it does.
