Organizers call it “part science fair, part county fair” and the “greatest show (and tell) on Earth.” Artists, scientists, educators, engineers, basically tinkerers of any kind, show what they have created, and discuss how they did it. These do-it-yourselfers will also lead exhibit demonstrations and hands-on workshops. If you think it’s just for engineers, think again. And go see two featured presenters include musical performances from musician Jecorey “1200” Arthur and Louisville Orchestra Music Director Teddy Abrams. You will sure to be amazed and inspired by the ingenuity of these master makers. —Aaron Yarmuth
