Bubble Festival

Children will learn how to make bubble blowers using everyday objects like straws, yarn and potato mashers during the Chesapeake Children's Museum's first festival dedicated to the bouncy subject. Museum director Debbie Wood and director of programs Renee Spears will lead children ages 2 and older in lessons on "bubbleology," the science that explains how bubbles work. When they blow bubbles, Wood said, they'll have fun and learn elements of science, including the fact that hydrogen and oxygen combine to make bubbles round and the fact that bubbles are a prism for sunlight. "There's so much to learn in the world, and learning can and should be fun," Wood said. "Here children get the true experience of joyful learning." 10 a.m.-2 p.m. today. Chesapeake Children's Museum, 25 Silopanna Rd., Annapolis. $3. 410-990-1993 or www.theccm.org.
