Two fun new exhibits in the Seattle area: on Saturday the Museum of Flight opens “Style in the Aisle: The History of Fashion in Flight,” a display of flight attendant uniforms from their extensive uniform collection. And yes they have the infamous Pucci+Braniff space bubble headgear. At the Pacific Science Center, kids can learn all about trees from the inside out, sit in a giant bird’s nest, crawl through a log, and go inside a huge acorn.
