How to Make Homemade Water Balloon Launchers & Water Guns

Hitting a target with a water balloon is more accurately accomplished using a homemade launcher. You will need some cardboard, a few items from a hardware store, along with a garden hose from your backyard or garage. You also will need a few tools commonly found in most households, but this task requires no special skills. Your water balloon launcher will also be able to serve as a water gun when no balloons are present.

Things You'll Need

• Newspaper
• 11-by-14-inch cardboard, quarter-inch thick
• Duct tape
• 6-inch-diameter PVC cap
• Portable drill
• 2-inch drill bit
• Water-resistant spray can
• Sprinkler gun
• Garden hose
• Balloon

Instructions

1. Place a sheet of newspaper on a table to protect the surface. Place the PVC cap on the newspaper. Drill through the center of the PVC cap with the portable drill.

2. Place the cardboard with the 11-inch side facing you on the newspaper. Spray the cardboard with the water-resistant spray. Let the cardboard dry for a day. Turn the cardboard over and spray it with the water-resistant spray. Let the cardboard dry for a day.

3. Roll the bottom of the cardboard over to the top to loosely form a tube. Insert the PVC pipe cap in one end of the tube. Tighten the tube around the PVC pipe cap.

4. Close the sides of the tube with strips of duct tape. Wrap duct tape around the PVC pipe cap to secure it inside of the end of the tube.

5. Go outside in your backyard. Place the nozzle of the sprinkler gun into the hole in the PVC pipe cap. Wrap strips of duct tape around the nozzle of the sprinkler gun to secure it to the PVC pipe cap.

6. Hold the open end of a balloon over the end of a water spigot on the side of the house. Turn the water valve to fill the balloon with water. Turn off the water valve. Tie a knot in the end of the balloon.

7. Screw one end of a garden hose to the sprinkler gun. Screw the other end of the garden hose to the water spigot. Turn the water valve fully clockwise.

8. Hold your water balloon launcher with the open end facing up. Drop the water balloon into the open end carefully so that it slides down to the other end.

9. Aim your water balloon launcher at a tree or rock in the backyard. Squeeze the trigger of the sprinkler gun to fire the water balloon at the tree or rock. Keep pressing the trigger of the sprinkler gun to shoot water at the tree or rock.

Tips & Warnings

• Party balloons will hold more water than the regular ones sold in drugstores and toy stores.

• Shooting a water balloon at a person who is not expecting it can result in a civil or even criminal complaint against you.
