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.

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.

wat type of not is good???? cause hard for me doing a simple water ballon knot
Prop (author)  acrafty6 years ago
its just a normal tie it before theres any pressure on it so its just like tying string
Correction: It is called an overhand knot.

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)  Rock762222 years ago
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.
