This water balloon launcher can launch any size balloon close to 400 feet. And, it is completely silent for unexpected bombardments!
This is my sweet water balloon launcher. It is eight feet tall, and three feet wide. It is anchored to the ground to four earth anchors, each rated to 1200 pounds. The only thing hindering the distance of the balloons is the friction between your feet and the ground as you pull it back. We have tried walking backwards on a ladder, and it worked beautifully to up the distance greatly. We plan to increase the size of the bands soon. In total, the project cost me close to $100. Well worth it if you ask me!
