Picture of office supplies grappling gun
Ever notice how secret agents and spies get all the cool gear? Now you can, too!
Make your own mini grappling hook out of everyday office and household supplies, then let let loose on a top secret mission from Her Majesty's Secret Service.

This grappling hook design was built from the new book Mini Weapons of Mass Destruction 2. This book has over 30 types of weapons and gadgets which can all easily be built with office or household supplies, most of which I had on hand already! I chose to build a personal favourite, the grappling gun. I recently got my hands on a copy of this book, you can read my review here.

Enough talk, let's make a mini grappling hook!

Step 1: Tools + materials

Picture of tools + materials
  • masking tape
  • needle-nose pliers
  • hot glue
  • drill + bits / saw

  • floss container (full)
  • pencils x2
  • ballpoint pen (with removable back)
  • clothespin
  • cap from large marker
  • rubber band
  • pill/medicine bottle
  • paperclips

how do i remove the pen bottom

you can either cut it off or use your teeth and pull it out :P

BenjaminC6 made it!4 months ago

so i didn't have all the items you listed, but i had some substitutes. instead of a pill bottle i have a marker cap. instead of the marker cap on the top i used the center of the spool of dental floss. it isn't too great, but i think if i tinker with it i could make it better. thanks for the design!

Substitution is the name of the game! Glad you could make it work with the supplies you had. You should upload your videos to YouTube and share the results with other, too!

This is freakin beast! Best thing I've seen on Instructables for a while. (Yes, I've been creeping for five years or so without an account. X3)
This is the coolest thing on instructables
Made my own it probably doesn't shoot as far but it is more concealable

Does anyone know where I can get a travel size plastic bottle 3.4 fl. oz. or smaller?
Teachers beware that's hilarious

I made one too.. I just lost it in our old house. My brother shoots it and makes the hook grab onto my shirt and he pulls me.. It's kinda annoying when my brother uses it.. But once I use it it becomes less annoying and more cool and spy-like.
totally one hindered and infintity percent awesome

That, my friend, is pure epicness. One more reason to stall on my homework, consider me inspired. If you'll excuse me I'm going to search my house for supplies. I'll take pictures.
Done. Sorry for the bad quality, I took this picture with my webcam.
I also wasn't able to keep the hooks on long enough to taker the picture- whoops!

Ahhh... stalling on homework.. Im doing it right now!
This is my grappling hook gun. I didn't have a wooden clothespin so I just release the elastic band by hand. I only have 2.7 m of floss though. But it shoots really good.
I made one too, but I didn't have a wooden clothespin so I had to use a plastic one. Now my hook don't shoot that far :(

i added another barrel to mine so it shoots pencils as well as the grappling hook! i hid the string, too.
mikeasaurus (author)  Magh2os3 years ago
Awesome, thanks for sharing!
Where/how did you hide the string? I would be neat to show us how you made yours on your project page.

For posting your version of this project you've been awarded a 3-month Pro Membership and a digital patch!
the string is curled up inside the M&M tube handle, and here is a hole running through the lid and pencils base where the line comes out! i duct taped it so i could still use the tube without much difficulty.

You know what'll be cool, if you used a motor and attached it to the dental floss. That way, it'll be easy reloading.
My black and green version of the grappling hook. didn't shoot very far :( ,but it looks cool:)
Toasty22223 years ago
Awesome instructable! I have tried to make many office supply weapons but none of them end up actually working. This one however, successfully shot the grappling hook thingy 5 meters!!! Hooray!
I think ill use a spool of thread
AshleighLm3 years ago
Didn't shoot to far. But I loved making it.
mikeasaurus (author)  AshleighLm3 years ago
That looks pretty good! You should try it again with different materials and see if you can get it to shoot farther.

For posting your version of this project I'm awarding you a digital patch and a 3-month Pro Membership to Instructables; enjoy!

Is there a reason for the floss? Or can you use normal cotton string?
mikeasaurus (author)  AshleighLm3 years ago
Floss is thin and light-weight, but any thin string would work well.
instead of a pill bottle I used a film canister. it works just as good.
good idea, can you share pictures of your version here so we can see?
I didnt take any pictures before it got thrown out sry

Dude I have that same book it is awesome
What is the name of the book
Mini Weapons of Mass Destruction 2
i just made one and they are pretty awesome! I used a pen lid for the handle and i didn't put paper on the hooks. It doesn't go too far but I guess thats because I used 2m floss not like 10m
mikeasaurus (author)  NanoRobotGeek3 years ago
Nice! maybe you could try doubling up on the elastics to make it shoot farther?
I'd like to know your results!

Enjoy the patch and 3-month Pro Membership!
How do I see my patches??
Thanks for the tip. I tried and now it does shoot further!!! Thank for the awesome instructable!

I made the hook. It is quite useful- i pulled down some paper airplanes stuck on a ledge with it.

This is my version of the grappling gun, the grappling hook launches from the center of the launcher rather than the exterior. I don't know if this makes it a better launcher but, I personally, however like the look. Thanks for the inspiration!
mikeasaurus (author)  RoboTable3 years ago
Nice build, I like the curled, unfinished paperclip hooks.

Thanks, I even made an instructable for it.

the man who made this instructable?
Awesome Instructable. I made it but with a minor adjustment i used a pill bottle which has to be opened at a certain point meaning it just keeps spinning so it acts as a reel.
mikeasaurus (author)  The Science Guy3 years ago
Neat idea with the reel, how far does it go?

Thanks it goes around 5m!
freeza363 years ago
I made a couple earlier today, but i took out the grappling hook idea, meaning I made pencil launchers. Also, instead of using a clothespin, i used a binder clip

Whoa, that first one looks like it could be quite the launcher.

What if you modified the floss dispenser so that the floss just came off the spool in the dispenser, and attached a lever so that it could be re-wound?

You should make it and show me how!

Sweeeeeet I'm always looking for new ways to annoy the people I work with.

With a range of 6 meters I could easily fire this at someone's desk and start yanking stuff off of it!

Having been fortunate enough to receive this exact model as a gift, I have to say that this truly is a fantastic weapon! Its now my most preferred method for keeping annoying song birds away from my dorm room!
