Slingshots have been making us smile for decades. Well, a couple summers ago I had the chance to use a water ballon launcher and it was pretty impressive. The issue was that you needed three strong (and willing) people to operate it. I decided to build a base for this launcher so that it could be operated by only one person. Plus this can be used for launching a variety of things. We decided to make a pyramid of Homer buckets and try to knock them over with a small soccer ball!
