The Fiske Public Library will host “Bubbleology: The Secret World of Bubbles” Saturday at 10:30 a.m. in the Sweatt meeting room. Keith Michael Johnson’s program explores the science, art, and presence of bubbles in everyday life. The hourlong presentation is aimed at children ages 4 and older, although toddlers are welcome if they sit in their caregivers’ laps. Tickets are available at the library’s circulation desk; the program is free, but canned-good donations for the Wrentham Food Pantry will be accepted. For more information, call the library at 508-384-5440 or visit www.fiskelib.org .
