NEW YORK – Danish artist Jeppe Hein brings whimsy and water to Brooklyn Bridge Park this summer with “Please Touch the Art,” a three-part series of interactive sculptures that spans the entire length of the park.

I recommend starting at Pier 5, and walking north toward Mirror Labyrinth (above), rectangular stainless steel planks, all of uneven heights – to mimic the Manhattan skyline they face – arranged in a circular maze, looking as if they’re growing out of the park, just like their grass neighbors. The mirrors make the paths between them look infinite, a portal to another world. Unfortunately, no Narnia-like journeys have been reported, but better than that is watching how visitors interact with the mirrors. Children hug the planks, try to pry them out; parents try to pry the children off the planks, and the whole world takes an Instagram photo.

Equally photo-worthy, and even more refreshing, is Appearing Rooms. On a wooden platform steps from the Pier One entrance, walls of water systematically rise and retreat, creating rooms on all four sides.

I loved how the presence of a sprinkler turned visitors of all ages into frolicking children. Under the banner of art, even the 30-something among us feel free to finally run through a set of sprinklers on a hot day, a desire most of us must repress under the equally powerful banner of not being seen as creepy in a children’s playground.

Connecting Mirror Labyrinth and Appearing Rooms are Modified Social Benches, 16 orange benches spread across the park, and threaded through and around Appearing Rooms and Mirror Labyrinth. Some, like the figure 8 or the arch, are less of a bench than a jungle gym for toddlers, though said toddlers’ parents can comfortably collapse on most.
