If this morning’s Walk, Rock & Run leaves you aching for even more diversity doings, head over to the Cleveland Museum of Natural History for the World Culture Festival. From 10 a.m. to 3 p.m. you and the kids can make masks, get your faces painted, take some swipes at a piñata, learn origami, and enjoy ethnic dance performances. While you’re there, take in the Mythic Creatures: Dragons, Unicorns & Mermaids exhibit; cough up another $4 and catch a planetarium show. The culture comes free with regular museum admission of $10 for adults; it’s less for kids, students, and seniors. Tickets are available at the door. But don’t be late: A free, one-of-a-kind Museum kite goes to the first 1,000 visitors.
