How to Make a Water Balloon Sling Shot

Make a three-person water balloon sling shot and watch your balloons take off. Large slingshots are perfect for open spaces where the only living creatures present are the launchers and where the only targets are inanimate objects. These mechanisms can cause serious and permanent damage and even death if aimed at people or animals. Use them responsibly.

Things You'll Need

Funnel
16 to 20 feet of rubber or latex tubing
2 washers
3 feet of rope that will fit through the funnel
Power drill
Drill bit
Water balloons

Instructions

- 1
  Flip over the funnel so it stands on its mouth on your work surface.
- 2
  Drill four holes in the funnel just above the rim. Drill two holes on one side, 3 inches apart. Drill the same-sized holes on the opposite side of the funnel. The holes should be larger in diameter than the tubing.
- 3
  Cut the tubing into two segments. Each segment should be eight to 10 feet long.
- 4
  Thread one section of tubing through one set of holes so that the loose ends are on the outside of the funnel. Repeat with the other segment through the other holes.
- 5
  Tie the rope through the washer and insert it into the funnel so both rope ends come through the narrow end of the funnel. Hold the washer in place by attaching the other washer on the exterior of the funnel and tying a knot in the rope. This will serve as the handle for the person launching the balloon.
