Cowabunga! Stay and play late on July 7. Families can explore the museum's permanent and temporary exhibits, and enjoy activities inspired by the traveling exhibit, Nickelodeon's Teenage Mutant Ninja Turtles: Secrets of the Sewer. Families can make mutagen slime in the S.T.E.A.M. Cave lab, meet a turtle in the Science Showplace, build a sewer and make turtle masks in the TMNT exhibit space, plus enjoy pizza samples from Godfather's Pizza. Activities are included with regular museum admission, and available while supplies last. Exhibit sponsor Godfather's Pizza will also have pizza available for purchase, as well as a photo opportunity with The Godfather.
