Huge Ball and Socket Joint made by YouTuber Edu Puertas is an piece of work. He travels to his local store and buys some kind of lawn bowling balls and proceeds to drill, cut, mill, and weld big pieces of metal and turn it into this amazing piece of artwork. Now how practical is it? Well, I would guess that it would be fun to play with and build a giant sculpture or better yet huge puppet. Edu Puertas has many other stop motion videos about building all sorts of different things. Check out the video below and be sure to say hello to Edu Puertas on Youtube. He deserves the praise for this awesome build.
