So how do you top a bunch of excavators playing the world's most massive game of Jenga? You put them to use doing what they were designed for: building stuff. Except stuff, in this case, happens to be the world's tallest sand castle towering over 12.5m.
The gigantic sand castle -- which was endorsed by the Guinness Book of World Records as the world's tallest -- was partially constructed by five CAT earth movers, with humans taking care of the creation's finer details. It's of course all a big publicity stunt for CAT and its equipment, but anyone who's ever found themselves staring at a busy construction site will certainly appreciate the finale here when the giant machines turn on their creation and bring it crumbling down.
