 Check this out. You're looking at the world-famous Sphere Venue in beautiful Las Vegas. And today, we're proud to announce the winners of a first-of-its-kind contest to display work there. Now, here's some of the work. It's 4th of July-themed creations from students ranging in age from elementary school through college. They were submitted as part of what's called the XO Student Design Challenge in Las Vegas. Chris Van Cleve spoke to the students about showing their work on such a massive scale.
