Picture of Pull Pin Nerf Grenade

This instructable will teach you how to make a pull pin nerf grenade that explodes on impact and has a 3 to 5 foot blast radius.It sprays 4 streamline nerf darts.This is non-pyrotechnic so you can use it in indoor nerf wars and battles.

Step 1: Matierials

You only need a few household items.

1. 4 streamline nerf darts
2. 2 small rubber bands(about the size of the ones in the picture)
3. 1 key ring

Step 2: The Pull Pin

Picture of The Pull Pin

Take one of your small rubber bands and put it on the key ring like so.

Step 3:

Take your four darts and make a rectangular prism out of them like the picture. Fold the rubber band like an eight then over to make a smaller and tighter one.Wrap that around the bottom of the darts like so.

Step 4: The Other Rubber Band

Picture of The Other Rubber Band

Wrap the other rubber band around the tips or or close to the tips like the picture. Before you do that do the rubber band thing we did in the last step.

Step 5: Done

Now the grenade should not go off if you throw it. To set for detonation pull the pin with the rubber band off and throw the grenade (tip first) hard and at a hard surface. or at your enemies >=) mwahahahahaha!!!!!!!!!!!!

Sweet. The only thing i recommend to change it to use 7 darts instead of 4. More explosives! :)

SalmanR (author)Pichu472014-12-21

The more darts, the better (guess what happens with 30?) but I can't make that many because then I run out of ammo for my guns :(

GermanMan32 (author)SalmanR2017-03-16

I feel ya

frost360 (author)Pichu472012-03-20

cool more exsplosiveness

kve23 (author)Pichu472012-01-31

its kinda hard to make one out of seven though... its also kinda sensitive...

the_ickynator (author)2016-06-08

also try 6 disc darts with a rubber band around them.

Plo Koon (author)2011-04-01

Do they HAVE to be streamlined? RSVP!

SalmanR (author)Plo Koon2014-12-21

No, I tried it with Elite Darts and it still worked, but I think the blast radius was down a tinch. And by the way, Elite Darts are better than streamlines because they shoot farther and are more compatible.

kve23 (author)Plo Koon2011-04-02

yes they do

Plo Koon (author)kve232011-04-06


kve23 (author)Plo Koon2011-04-07

why do u not have streamlines

Plo Koon (author)kve232011-04-08

I lost all mine.

kve23 (author)Plo Koon2011-04-16

that sucks cuz streamlines are the best. you should go to walmart and get u a ammo box. there kinda pricy but u get 100 streamline darts and an ammo box to put them in

Plo Koon (author)kve232011-04-18

you know how much $ it cost?

Arch Angel 42 (author)Plo Koon2012-07-04

around $15

kve23 (author)Plo Koon2011-04-24

kve23 (author)Plo Koon2011-05-25

alarson3 (author)kve232011-06-28

diymonger (author)alarson32011-07-22

frost360 (author)2012-10-03

I havent made it yet :(

frost360 (author)2012-03-20

ill try it but i dont get how u r surposted to use it
because if u pull the keyring bit it will make the bullets fall out (strait way)!!!!

kve23 (author)frost3602012-09-15

Not if you get it right. The bottom rubber band is only there so you cant bump it and set it off

mater nerf gun (author)2012-06-29

i tried 50 and it worked when i was at war i hit out 6 people

mater nerf gun (author)2012-06-29

i tried it it went 2 inches

maxomega (author)2011-09-06

Wow! easy, cheap, and works! Great work man!

kve23 (author)maxomega2011-09-15

Thanks,glad it worked for you.

atomiclegocreations (author)2011-07-24

is this easy to use with the grenade launcher Meanbean made?

what do you mean by easy

like you can put these in it and when they land they will explode.

i guess so ive never made meanbeans thing

*gasp*! this goes very well with nerf, but the grenade launcher can be an essential

mebuildgunz (author)2011-06-13

i made it with 10 darts

kve23 (author)mebuildgunz2011-07-13

i made a 7 dart onefor my insanely huge nerf cannon

hcho (author)2011-06-21

You can also use clip system darts you know. And just get a 16 pack. Why get a whole box of them?

kve23 (author)hcho2011-07-13

stream lines are clip system darts and the box is my opinion cuz i have alot of nerf guns that take streamlines

gentoo47 (author)2011-06-12


hakeye (author)2011-04-29

i made this my self and i didnt work! but i found tieing the rubberbands together is easyer so when you toss you can get you gun.

Plo Koon (author)2011-04-12

Is this really an effective wepon in a hallway nerf battle? Can you lob it with good results? Please reply.

kve23 (author)Plo Koon2011-04-16

it would be awesome in a hallway battle and it doesnt work very well by lobbing it but it will still do something

Matrix-technician (author)2011-02-21

I want to see someone make an underbarell grenade launcher for nerf tactical rails.

kve23 (author)Matrix-technician2011-02-21

look at maxxxem's post on grenade launchers for nerf

patriots8888 (author)2011-02-16

you know want i want to see, a nerf gun that shoots these (well with the pin removed already) that would be so awesome :)

kve23 (author)patriots88882011-02-16

im working on an air cannon with a tripod so its a turret. or look at maxxxem's pics for ideas.

kve23 (author)kve232011-03-10

i finished the cannon and it turns out that if you make the grenade with seven darts and fire it at a car its blast radius is like 10 feet. not to mention the center dart ripped in half on impact >=D

patriots8888 (author)kve232011-03-11

cool add a pic or vid
