Introduction: The Porta-Pault Water Baloon Launcher (update!)
This is my entry for the launch it Contest! Me and my Brother (Macky D on instructables), had our own launch it contest to get us motivated to make something for this contest. I eventually won by over doing it. Through all experiments and changes, the final design is what you see on your monitor.
The final design shoots a golf ball sized water baloon 120 feet. I can't wait to shoot things like rocks, tennis balls, and much more. In the comments, put what you think it could shoot. I am not really sure how high it shoots, for I have nothing to measure it aginst. Photos attached show how far it shoots.
