With the thrill of opening presents over, kids may think January is bereft of fun. But magician schoolteacher Mike Della Penna aims to conjure up all manner of mystery and wonder—and teach kids about math and gravity, too. Kids will get to participate in tricks and other activities like writing a poem together on stage. Della Penna will perform his free Winter Magic Show on January 7 at 11 a.m. at the Healdsburg Regional Library in Healdsburg and at 2 p.m. at the Rincon Valley Library in Santa Rosa.
