An Arvada girl will have a helluva Halloween costume this year, thanks to Prof. Jeff Ackerman and the Mines Maker Society. Dr. Ackerman and Mines ME students Claire Thomas and Bradley Jesteadt unveiled the one-of-a-kind costume earlier this week, drawing inspiration from Ursula (of Little Mermaid fame). Check out this 9News segment to learn more about the project and hear from the students behind it.
