Whether you're curious about snakes, fascinated by snakes, or wary of snakes, you're invited to an hour-long snake-a-thon at McNally Jackson. Kids can create their own nest, den, pit, or knot of snakes, maybe even a rhumba of rattlesnakes, using various brilliant and textured materials. Our featured book: Snakes by Patricia Demuth. Hosted by Yvonne Brooks. All ages welcome. Free.
