Introduction: Paintball Grenades

Picture of Paintball Grenades

Re usable, cheap paintball grenades and are easy to make

Step 1: Materials

Picture of Materials

1.Sergical tubing (I got mine from a friend who was in physio tharapy and my brother got some also from a physio tharapist but im sure theirs other places to get it)

2. Coat hanger (straightened out)

3. Air soft BBs (the 6mm ones, it shouldn't matter what weight)


5.Water gun pump(out of the gun). Iv also used nerf gun peices but their harder to use.

Step 2: Tubing Length

Picture of Tubing Length

Cut the tubing into peices that are around 10 or 11cm

Step 3: Tying the End

Picture of Tying the End

Tie a knot in one end each peice of tubing so that the one end is sealed. make sure that it is tight and close to the end.

Step 4: Make the Collar

Picture of Make the Collar

Cut a peice ooff the open end of the tubing to creat a small ring to tubing. Take this and put it over the tube near the end.

Step 5: Pin Hole

Using a pin, make a hole just above the collar for the safety pin to go in

Step 6: Getting Your Paint

Picture of Getting Your Paint

Take the paintballs and put them in water for a few minutes. After you take them out they should be soft. Cut them open with a knife of scissors and squeeze the paint into a disposable containter. Iv also heard that you can boil them. Iv never tryed it my self but it might work.

Step 7: Filling the Grenade

Picture of Filling the Grenade

Put the open end of the tube over the end of the pump as far as you can. Fill the cylinder with paint and push the paint into the granade with the plunger. If you have a pump from a water gun it should have a valve in it but if it doesnt you have to twist the neck of the grenade befor you take the plunger out to fill it again. Fill the grenade with two pumps of paint and one of water (to save paint). If it gatheres in the middle push it to the sealed end.

Step 8: Putting in BB

Picture of Putting in BB

Twist the neck of the tube just above where the paint is so that its sealed off. Pull the tube off of the pump while keeping it sealed. It should not leak. Take one BB and push it into the tube till it is just below the collar.

Step 9: The Safety Pin

Picture of The Safety Pin

This should have been made befor putting the paint in the grenade but i can figure out how to insert steps. Using plyers make a safety pin out of coat hanger. To brake the coat hanger just bend it back and forth several times fast and it'll break. If you want you can also add a ring to the pin. Once the the grenade is filled and you've put the BB in, keep it sealed and push the safety pin through the hole you made above the collar. After this you should be able to un twist the neck and your finnished.

Step 10: How to Use It

Picture of How to Use It

To use the grenade carefully pull out the safety pin and throw. What should happen is when the pin is in any extra pressure in the grenade pushing against the BB (like the pressure from dropping it or bumping it while running) will try to push the BB out but the pin will stop the BB. When you remove the pin, as long as your carefull the BB will stay in the neck of the grenade and the collar will help it stay there. When the grenade hits something the extra pressure will push the BB out and the paint will be sprayed every where in the area. The pressure for tube will cause the grenade to spin so the paint should sray all around. If you keep the pin and find the empty grenade you can re-fill it, put a new BB in and you can re use it. The splatter zone (area that the paint covers) varies but is usally around or over 1.5 meters. Have fun!

difference between making these and using waterballons will it work

Prop (author)lukee19862017-05-13

Ummm is your questions why are these better then water balloons? Water balloons wouldn't work cus on impact all the paint would just sort of splatter flat. When these impact they stray around so giving a way higher change of hitting someone. Also these wont pop by accident while in play and my guess balloons would.

rocketdork (author)2007-02-14

wher els can i get this toob josh

home depot or lowes

Prop (author)ManchesterUtd.2009-11-10

Iv never seen it at either

burke.harris (author)Prop2017-01-28

It's in the plumbing section near where all the other types of 1/4", 1/2", and 3/4" vinyl tubing is coiled up and sold by the foot.

ManchesterUtd. (author)Prop2009-11-11

Oh, well i dont know what to say. i got mine at home depot

rockadio101 (author)rocketdork2011-02-16

kinny drugs its colled a comdom

codongolev (author)rocketdork2008-06-26

you could use a balloon. (the long thin kind)

Prop (author)codongolev2008-07-21

no you cant

naruto the ninja13 (author)Prop2010-04-08


Prop (author)naruto the ninja132010-04-08

Cus it too big around to hold a bb and doesn't have enough pressure

codongolev (author)Prop2008-07-22

ummm..... okay.

Prop (author)rocketdork2008-07-21


noahmadd (author)2015-08-30

If You don't have a water gun pump you can use a 60ml plastic syringe.

JulianAzz (author)2015-08-13

I like it!

Trolling paintballer (author)2013-02-24

I am working on how to make a small paintball practice field. Need some help and it would be asome if someone is interested. Also the grenade really works and is very useful.

The Greene (author)2012-07-29

Vary nice ill stop buying the stupid tippmann, Bt Grenade crap

gordonfreemanisalive 23 (author)2012-07-09

pretty cool , man.

djl2 (author)2012-06-27

it sounds sweet

acrafty (author)2009-01-06

wat type of not is good???? cause hard for me doing a simple water ballon knot

Prop (author)acrafty2009-01-06

its just a normal tie it before theres any pressure on it so its just like tying string

Jarheadicus (author)Prop2012-04-16

Correction: It is called an overhand knot.

Rock76222 (author)2012-04-01

So, if I were to pull the pin and put this grenade in a rocket launcher that fires it across my yard at high velocity, will it keep from exploding until it hits it's target, or will it burst inside my launcher the moment i pull the trigger

Prop (author)Rock762222012-04-01

Good question..... no idea. All I can suggest is to try it. I think if you put lots of packing behind in it would probably work. Or you could try a modified way of pinning in and tethering the pin to the launcher. Ya do that... instead of putting a pin through the end just fold the end over and put a clip (like a nose plug type clip) on the end that will come off easy and just tether it. you dont need a lot to keep the bb from slipping.

kylekosan23 (author)2011-07-22

ya a vid would be nice

Prop (author)kylekosan232011-07-24

Considering I made this instructable 5 years ago..... its not gona happen. And there is a video of it going off.

kylekosan23 (author)Prop2011-07-25


pbman123 (author)2011-06-18

do you have any idea what wall thickness you used or does it not matter

pbman123 (author)2011-06-07

where do you get the tubing. and also could you add a video so i can see how well it works?

Prop (author)pbman1232011-06-07

Look through the comments to find where to get it and there was a video somewhere on here but I dont have one anymore if its not here anymore.... sorry.

theREALcybercat (author)2011-02-06

Iis this could work with water as well as paint?

Prop (author)theREALcybercat2011-02-06

Yep.... when I was designing this I used water to do all my tests.

Prop (author)2011-01-15

Mine are still better.... Lol

djlolypop (author)2010-03-27

i when u use it pick the stuff up and make like a good place to put it in then when u get back home make more

spenfisher12 (author)djlolypop2010-12-24

what does your comment mean

Prop (author)spenfisher122010-12-24


Rdav- (author)2010-10-30

Could you use a bikes inner tube for the tubing?

Prop (author)Rdav-2010-10-30


john209 (author)2010-10-07

what diameter is the tubing?

Prop (author)john2092010-10-07

the answer to that is already in the comments

migel (author)2010-07-28

you can get surgical tubing at most hardware stores

wectangle (author)2010-05-20

the other advantage to using the surgical tube is its shape. you should be able to put one in your ammo pod to protect it when out in the field...

tommyskater1 (author)2007-07-10

what kind of tubing do you use?

switchpaw (author)tommyskater12009-09-14

between 20 and 16 gauge wire works for the pins.

Prop (author)tommyskater12007-09-08

Surgical Tubing....Sorry it took so long to respond, for some reason I didn't get a notification.

switchpaw (author)Prop2009-09-14

or latex tubing as it is known in hardware stores.

rocketdork (author)2007-02-14

where can i get the pipe

switchpaw (author)rocketdork2009-09-14

you can just use a large syringe, you can get them from your local pharmacy (Rite aide, Wall Greens)
