It’s time for bubbles! No, not champagne. Soapy, blow-and-pop bubbles. This favorite childhood diversion will be the highlight of the Children’s Museum of Sonoma County’s seventh anniversary party, the Bubbly Birthday Bash. The event will be held on June 19, 9 a.m.–4 p.m., at the museum’s newly reopened Science and Imagination Gallery, and in Mary’s Garden, also on its grounds. Admission is $9–$12; babies 0–11 months and members get in free. Make a reservation at cmosc.org/visit.
