Paintball Grenades!

Paintball grenades are a huge advantage in the sport of woodsball. It's easy to get that pesky tango out of the bunker when you toss a paint spraying balloon at them. In this post we'll show you how to make a quick and easy grenade that's a fraction of the cost of the commercial version.

Our paintball grenades are 100% reusable, take only a few minutes to make, and cost only around $.50 per grenade in materials. That sure beats the pants off the retail grenades that sell for $8 to $10 a piece. Check out the how-to video or jump down below for full details.


  • 1/4" Latex tubing (5 inches per grenade)
  • 4" Cable ties (3 per grenade)
  • Fishing Line (10 to 12 inches per grenade)
  • Wire Coat Hanger or similar wire (for arming pin)
Tools you'll probably need:

  • Wire cutters
  • Needle nose pliers
  • Diagonal cutters
Assembly instructions:

  1. Cut a 5 inch section of latex tubing. Tubing can be cut using almost anything sharp, we like using diagonal cutters. 
  2. Seal the bottom of the grenade and add the carrying loop. Start off by loosely "ratcheting" two cable ties to one or two clicks. Tie one end of the 10 to 12 inch piece of fishing line to a cable tie. Pinch the very bottom of the latex tubing into a small fold with one of the ties stuck into the fold. Use the second tie that has the fishing line attached and secure the fold tightly while leaving the carrying loop tie loose.
  3. Prepare the top of the grenade with the release ring. Fold the top portion of the latex tube in half and ratchet a cable tie just barely tight enough to hold the latex folded together. The tie should be loose enough to slide off with a little force, but tight enough it will not fall off. 
  4. Create the release pin. Take a short piece of wire (about the thickness of a coat hanger) and cut a section off roughly and inch in length. You can use needle nose pliers to bend one end of the wire over to add a slight grip to pull the pin out. Next slide the pin in just above the release ring in the fold. 
  5. Fill the grenade. Take the pin and release ring off and use a filling device (check out ours) to fill the grenade to desired level. Note that the more liquid you put into a grenade the less stable it becomes and overall performance can degrade. It's best to play around with fill levels and find the sweet spot. Once the grenade is filled, fold the top of the tubing, place the release ring over the fold and stick the pin into the fold just above the release ring. Do not allow the release ring to slide up against the pin, it could allow the fluid to leak or spray out. 
  6. Find some cowering opposition and try out your new toy!
This is a very simple grenade design. In fact it's pretty much the same thing you will go out and spend ~$10 to buy. The spray pattern in my opinion is quite good and will be very useful if thrown to the side of a bunker.


    1. hey mod guys i'm a paintballer and after seeing your video on the paint grenade I realized yea it is a lot of money for a grenade so I made yours but mine leaked from the top part how did yours not? And what do you use for filler I use a mixture of boiled water cornstarch( you have to keep stirring the mix after it cools or it dries) and food coloring

    2. That video helped a ton I have been looking all over how to make one the right and your work perfect

      If you used the cable tie and pin method like we did, you may need to try tightening the cable tie up a bit. I will admit there is a sweet spot you have to find between a leaky grenade and one that doesn't go off at all. It take a little experimentation.

      Also, we haven't played around with fill materials yet. I do greatly appreciate the cornstarch, water and food coloring idea. We will certainly give that a try.

    4. Recognizing what air the paintball weapons work under is the key question. You can rapidly obliterate your paintball marker by utilizing the wrong gas. CO2 weapons need to keep running on CO2. Best paintball mask

    5. Your paintball gun has to be able to withstand running, dropping, bumping and rough treatment. It may serve to alleviate worries to know that most professional paintball facilities and game field owners lower that speed or velocity to about two hundred eighty feet a second, just to be on the safe side.
