Introduction: Cheap Airsoft Frag Grenades

Picture of Cheap Airsoft Frag Grenades

This is my first instructable, so hang tight. This grenade is obscenely dangerous, and should only be attempted by professionals or people with little-to-no attachment to their various extremities. Okay, maybe I'm exaggerating a bit, but this thing could easily take off a few fingers if you handle it improperly. Also, the noise is near-deafening, so watch out!

Step 1: What You'll Need:

Picture of What You'll Need:

1 Key-Chain Ring
1 Pack Strike-On-Box Matches
1 Commercial-Grade Firework
50-200 Cheap Airsoft BBs
1 Toilet-Paper Tube
Scotch Tape
Duck Tape

Step 2: Remove Striker Pads

Use the scissors to cut apart the match box and save the pads and top and bottom for later.

Step 3: Take Apart Firework

Picture of Take Apart Firework

Use the scissors to carefully disassemble the firework, removing the warhead from the rocket. Cut the main fuse off the rocket, and then discard.

Step 4: Seal the Tube

Picture of Seal the Tube

Seal one end of the tube with duck tape.

Step 5:

Picture of

Stuff a couple tissues or sheets of toilet paper down the tube.

Step 6:

Picture of

Add about half of the BBs to the tube.

Step 7:

Picture of

Bind all three fuses together with scotch tape.

Step 8:

Picture of

Assemble the triggering mechanism by taping the two strikers facing each other over the clip, and looping the ring through the end.

Step 9:

Picture of

Tape six matches around the fuses.

Step 10:

Picture of

Put the whole explosive together. Note: This mechanism can also be employed to great effect with smoke bombs. Just substitute caramelized sugar and KNO3 for a firework and BBs.

Step 11:

Picture of

Wrap the explosive loosely in tissue, and pack it in the tube on top of the BBs.

Step 12:

Picture of

Fill it up almost to the top with BBs, then pack another tissue in on top for good measure.

Step 13:

Picture of

Tape off the top, then decorate as you wish! Have fun fragging your friends and try not to blow off your hands! The blast radius is about 15-30m, and within 5, they will draw blood. Be careful!

also the blast area is about 35-40 feet and around 7-10 feet you will be bleading send a message if you want to find out how to make

chickenstrlp (author)2014-05-21

i made a similar on out of a fire cracker and stuck alot of bb,s to some air duct tape(the metal tape) and then wrapped it around the firecracker then put it in this pneumatic grenade launcher i made lit it and shot it. it wasnt all that loud but my brother had bruises all over where the bb,s hit him

striker149 (author)2014-01-07

I thought u where going to light it with the matches and then throw it no rig it

simplebotics (author)2013-12-05

That's what I was going to do with the flint parts on the ring. Good instructacble.

Jedrokivich (author)2013-09-24

Nice job! How did you type that after your fingers were blown off?

jayman242 (author)2013-05-05

I do like the thought of how you ignite this, thanks for the tip, I mean its pretty much fool proof and, yet still genuinely smart. Great job!!!

Who needs airsoft things instead use ball bearings and gunpowder for a low explosive and ammonium nitrate and diesel fuel for a slightly stronger explosive.  If you do this you probably wont have to worry about them the rest of the time.

xxcalebbxx (author)521932012-07-29

Black powder or flash powder would do you more good than gunpowder. and ammonium nitrate isn't very strong at all. Acetone peroxide would be a better substitute

Colonel Crunch (author)521932010-01-15

 Do you know how hard it is to get your hands on pure NH4NO3? Plus, I'm sure there are plenty of more efficient methods of killing people...

peters007 (author)Colonel Crunch2012-07-09

its not that hard to get Ammonium nitrate, you can get it out of instant cold packs the ones with the bubble in the middle

You do realize that the ANFO mix requires a blasting cap (illegal without permit) and primer charge (also illegal without permit) to detonate. Otherwise you are left with just a stinky heap of slush.

52193 (author)M4industries2010-07-19

Yes I do. I am capable of making both the class 2 blasting cap and the primer.

M4industries (author)521932010-07-19

Well, I'm not encouraging you to try this (under threat of lawsuit), but it seems to be within the realm of possibility for some.

thorpenny (author)Colonel Crunch2010-05-25

Its actually quite easy. just open up an instant cold pack. they go for about 40 cents a pop if you buy a bunch of em. just make sure the ammonium nitrate stays water free. it will absorb it from the air if left out.

52193 (author)Colonel Crunch2010-01-15

ammonium nitrate is the main ingredient in instant ice packs

Colonel Crunch (author)521932010-01-16

 I know that. But they take precautions to make sure it's not a viable oxidizer. Like the fertilizer.

52193 (author)Colonel Crunch2010-02-04

It is pure ammonium nitrate

Airsoftmaniac123 (author)2010-05-07

ummm the warhead term is only usually used on millitary spec rockets and the explosive on ur frag is like turning airsoft into a full scale war just u need real guns geezz that MONSTER is HUGE i wouldnt b suprised if it left a 4ft crater in the ground and blew a guys arm off and he lost a toe or 8, 5m it draws blood man ur insane

you would be lucky if it left a 1 inch crater

UNKN()WN (author)2011-07-12

I had to get cardboard, and put it at the bottom, then tape it, otherwise it just comes out at the bottom, plus, instead of using fireworks, i made my own explosive with a few chemicals so i knew wat i was dealing with. it drew a little blood to my friend, who started to shoot me point blank, all in all a fun day:) we were covered in holes by the end of the day

peters007 (author)UNKN()WN2012-07-09

what chems did you use?

bendog38 (author)2012-04-24

I have a new definition of a Bad Idea. Using a commercial-grade explosive to power a recreational-grade air soft charge has unforeseen lawsuit written all over it. I can see you detonating that and BB's going long distances, but at the same time, I see that if that charge lands and explodes too close, then the sound wave and shock wave can blow eardrums and/or cause unintended injury. I caution you that this is not a good idea. At worst, some one can be put in the hospital. At best, everyone on the field will be hit with at least one BB.


peters007 (author)bendog382012-07-09

ive had one of those big fireworks you see at firework shows hit me in the chest and go off (one of the mortar tubes fell over and shot into the crowd), it hurt A LOT and i couldnt hear for an hour or so but it wont kill someone. However thats not to say i support this idea, its a very bad idea, but the most dangerous part is the burns and the melted plastic.

Finally something that doesnt use baking soda and vinegar. Good job man! You should make a video of it.

h8864 (author)2012-02-02

i hate when people call it DUCK TAPE!!!!!!!!!!!!!!!!

Colonel Crunch (author)h88642012-02-02

It's Duck brand duct tape. In the same way that Band-Aids have to be capitalized because it's actually a brand name while the technical term is "adhesive bandage. The Duck Tape duct tape brand is owned by Scotch makers of Scotch tape (another brand name for a class of product) which in turn is owned by 3M, makers of Post-It Notes (you guessed it, another brand-name equivalent to a class of product). *The more you know!*

h8864 (author)Colonel Crunch2012-02-05

oh. there are just people that dont know about it.

PJPEEJ (author)2011-01-13

How long long is the fuse? I mean like how much time do you have to throw it if you pull out the pin?

Colonel Crunch (author)PJPEEJ2011-01-13

The fuse comes with the fireworks. You can test a few out by isolating the warhead and fuse and timing it. For mine, the fuse was approximately 5 seconds.

MrMadmonkey4 (author)2010-12-10

thats pretty cool man! i use it as a claymore and hide it pretty far away though so it doesnt hurt to much

caco caco (author)2010-07-19

cool because the projectile is powerfull than others instructables

deqwer (author)2010-06-14

have you ever light it on

Airsoftmaniac123 (author)2010-05-07

just cause my name is Airsoftmaniac123 doesnt mean i STILL WANT MY ARMS AND LEGS FOR THE REST OF MY LIFE.

So you don't want your arms or legs for the rest of your life? Lol. Look at what you wrote.

Dudeurdead (author)2010-05-18

My deatgh waiting to happen XD

mr. clean (author)2009-11-15

its is cool and all but jeez dont u think its a little much, it will draw blood at 5 feet?!! i wouldnt use this on my friends but mabey detonate it in a field or in a trash can but nice thinking i like the idea

pyrorower (author)mr. clean2010-05-18

He said 5m, as in meters. So really that's about 15 feet, so at five feet you would probably have BB's embedded in your flesh :P

mr. clean (author)pyrorower2010-05-18

 oh my bad but it still is really dangerous to use the charge from a bottle rocket.

aRejectedKitten (author)2010-05-01

wat kinda firework did you use?

teslafan100 (author)2010-04-27

5/5  very cool!

jeremy91511 (author)2009-12-21

waste of bbs if used incorrectly

teddy1998 (author)jeremy915112010-03-17

 yeah definetly

 How so? If you get cheap ones, there like five bucks per thousand.

josefu0 (author)Colonel Crunch2010-03-14

i got mine in a bag for a dollar

i meant in like airsoft wars. i mean you can only carry a certain amount of bbs. and they tend to run out quickly. co2 also, but you may get unlimited refills depending on the arena

 They would limit bb's that you put in grenades? I somehow doubt they can check that... If so, you might want to supply a squadmate who's armed with a sniper or something with these, then, as he wouldn't need quite as many.

ilpug (author)2010-03-01

this is a great looking grenade, but waaaayyyyyyyy to powerful. basically what this is is a cherry bomb in a can of bbs, to put it bluntly. i would make it the same way, but use a little TNT squib.  this is dangerous. maybe you could put rocs in this, wrap it in tape, and use it for fishing. as an experienced airsofter, i know that grenades are deadly but only when used right and when they actually work. i will post a ible soon about haw to make remote detonated airsoft mines.

yoyohead415 (author)2010-02-24

holy crap it draws blood? i want them to feel it not be injured by it but still AWSOME!!!!!!!!!!!!

arzarach (author)2010-01-16

did you ever experiment with fireworks before, well i have even if i was 12 and those things are fricken dangerous if you don't know what's in them ( such as gunpowder, explosive bbs to make the sparks, etc.) even though I'm 14 now and I still don't like messing with the big one's ( unless its for something amazing)
