The Brooklyn Children’s Museum is having the grand reopening for its $48M Rafael Vinoly design on September 20 and 21. In the meantime, the new exhibits and attractions are going up. In the photo above, Tim Watkins of May & Watkins Design, readies the “Splashdown” exhibit. It’s an interactive sculpture that “provides water for a stream full of hydraulics, dams, and boats in the museum’s new ‘Totally Tots’ exhibition for children 5 and under.”
