Earth Day in the Sky

Taking place over the entire course of the day, families can show up at the High Line for interactive exhibits and events ranging from a “salad-tossing” art performance by Alison Knowles (10am–1pm) to an urban composting station (11am–3pm). A special Earth Day in the Sky event (2–4pm) will include wildflower-seed-ball making, face painting and the creation of a mural. Free. All ages.
