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.

    Paint Grenade Fill Station

    In the world of scenario paintball/woodsball, having the tactical advantage is key. The ability to take out the opposition while they are behind cover or in a bunker is one of the ultimate goals when in a sticky situation. The best tool to use in such a situation is the grenade. Well, paint grenade in this case. In this post we'll show you how to create a simple fill station that will make creating paintball grenades easy.

    Check out our videos or you can read the full process below.

    List of supplies:

    • 2" Schedule 40 PVC Pipe
    • 4" PVC Pipe
    • 2" to 4" PVC reducer
    • 2" PVC Cap
    • 2" PVC Test Plug
    • 7 feet of 3/4" Clear Plastic hose
    • 3x 1/4" Nylon Barb couplers
    • 1/4" Brass Barb adapter
    • 1/4" Brass T adapter
    • 1/4" Brass Coupler
    • 1/4" Pressure Release Valve (150PSI)
    • 1/4" Ball Valve
    • 1/4" Quick Connect fitting
    • Thread Tape
    • PVC Cleaner/Primer and Adhesive
    • Plumbers Putty/Adhesive 
    • Zip Ties
    Tools you will probably need:

    • Drill with drill bits
    • Hacksaw
    • Utility Knife
    • Diagonal Cutters
    • Adjustable wrench
      Assembly Procedure:

      1. Cut a section of 2" PVC to use as the reservoir. We used a section roughly 3 feet in length and the size really just depends on how many fills you wish to perform before needing to refill the system. 
      2. Drill the holes for the air intake and fluid release barbs. Drill one hole two inches from the top of the reservoir and one in the center of the bottom 2" cap. 
      3. Cut the two barbs that will be fitted to the reservoir. Be sure to cut them next to the thicker solid center and discard the half that is no longer attached to the center section.
      4. Use the plumbers adhesive to attach the barbs to the reservoir. Use your finger and apply a dab of adhesive around the top (thicker part) of the barb and press firmly from the inside of the reservoir to adhere and seal the barb. Repeat the process with the hole in the bottom cap. Allow this adhesive to dry for at least 6 hours before attaching any hoses and let dry for 24 hours before actually using the system. 
      5. Use a rotary tool or file to remove the flange from the inside of the 4" to 2" reducer so that the 2" pipe can slide all the way through the reducer.
      6. Slide the reservoir tube through the 2" to 4" reducer so that the reducer makes a stand for the device. 
      7. Use the PVC Cleaner/Primer to clean the bottom of the reservoir tube and the inside of the bottom cap. Allow cleaner to dry for a few seconds. Then apply the PVC adhesive to both the reservoir and cap where they have been cleaned. Press cap onto the bottom of the reservoir firmly and in a twisting motion to attach the cap.
      8. Cut a short section of 4" pvc pipe to use as a riser for the base. Drill a hole large enough to run the 3/4" tubing through the riser and press the riser up into the reducer. The station should now be free standing and the bottom barb should not be touching the ground. 
      9. Build the air-in mechanism.Using thread tape, wrap the threads on the brass barb adapter, coupler, T adapter, and quick connect air fitting. Screw all components together as shown with the valve and air fitting on the right of the T adapter, barb to the left, and release valve at the top. Tighten with a wrench. 
      10. Connect the air-in mechanism with a three foot section of 3/4" tube using the barb adapters. The tube should fit fairly tight. Run the remainder of the hose through the hole in the base and plug into the bottom of the reservoir. Then insert the last barb fitting into the end as to have something to fill grenades. For good measure use a couple of zip ties and secure the fill tube to the reservoir so that the tube is higher than the maximum fill level. 
      The fill station works wonderfully. It is currently a two person operation but it's a lot easier than most of the previous methods we've seen. Someone will have to control the fill station while the other handles the fill of the grenade. Keep an eye for future posts on how to make the grenades, fill paint, and how to actually use them effectively.
