Kids and adults will have the chance to join the circus during the fifth annual Make a Circus show Saturday. The professional troupe will put on a circus and musical theater show featuring wire walkers, acrobats, trapeze artists and original music. Audience members will then participate in workshops on stilt walking, clowning, acrobatics, juggling and building human pyramids. Kids will use their new talents to take part in a final show with the professionals. The free event starts at 5 p.m. at El Toro Park on Los Alisos Boulevard, between Muirlands and Rockfield boulevards.
