Aerial Balloon Paintball Grenades

This was one of those things I've been thinking about for a while and finally decided to try.... at 2am of course. These work pretty well. They have about .5 to 1 second delay after you let go of them before they start going off. With a decent toss I could get them 15-20 feet before they started spraying. They make a very nice shower as the entire balloon empties itself in the air. The only concern I have about these is safely transporting them on the field. Doubling up the balloons should help.
Items needed -
- Small Water Balloons
- Popsicle Sticks
- Paint and Filler bottle
- Rubber bands
- Tape

Instructions -
1. Bend the popsicle stick in half without breaking it.
2. Fill the water balloon with your paint (or water for testing). Do not tie it off!
3. Use the popsicle stick like a clamp around the end of the balloon you would normally tie. Twist the balloon about a dozen times. It should look something like the picture below.

4. Use a small piece of tape and tape the rubber band to the middle of the balloon.
5. Fold the stick down so it's on the opposite side as where the rubber band is taped, then wrap the rubber band around to hold the stick in place.

All done. The end result should look something like the picture below.
