Things You'll Need:
- 1 foot of 1/8-inch rubber tubing
- Plastic clip tie
- Large syringe
- Children's paint (non-toxic)
- Hemostats
- Ball bearings
- Cotter pins
- Rubbing alcohol
- Rubber bands
-
Step 1
Pour the paint in a syringe. You can use children's paint such as poster or finger-paint. If you don't have any available you can melt some paintballs.
-
Step 2
Cinch the tubing in the center tightly and seal with the clip tie. Inject the paint mixture into one side of the tubing. Fill it until it is 2 inches from the top.
-
Step 3
Use the hemostats to crimp off the tubing. It should now resemble a sausage. Remove the syringe.
-
Step 4
Moisten the ball bearings with the rubbing alcohol and put it into the tube just above the hemostats. Stick a cotter pin above the ball bearing into the tubing. Let the alcohol dry before removing the hemostats.
-
Step 5
Repeat the process with the other side. Place a thin rubber band around the paintball grenade to maximize the spray coverage when it is thrown.
-
Step 6
Pull the cotter pin and throw the paintball grenade overhand at a firm object.
