There's a yo-yo craze going on up on the Iron Range. Today kids from all over the range competed in the Iron Range Yo Yo Tournament, braving adverse weather conditions to do their Loop-De-Loops and Around-the-Worlds. It's fun now, but it started as a science project in Hibbing. Washington Elementary science teacher Mike Misbauer began using the yo-yo to teach. He helped the kids start a yo-yo club.
