The circus arts aren't just for clowns anymore. They're not quite highbrow, but close -- not only do many regional teams and touring companies compete and perform across the country (Berkeley's unicycle basketball team is one of the best in the world), but some aerial feats developed in the circus have made their way into the fine-art world of dance. If it's about time you learned how to juggle, unicycle, aerobalance, slackline, or do anything else you've seen under the big tent (except, perhaps, elephant-riding), join the Berkeley Juggling Club at its weekly Wednesday meetings. Participation is free and open to all. On summer nights you'll find the gang at the UC Berkeley campus on the lawn north of the library (Memorial Glade); if it's dark or rainy, they'll be inside Dwinelle Hall, also on the UC Berkeley campus. 6-8 p.m. BerkeleyJuggling.org
freeIt's not every day that you get an opportunity to help propel a fifty-foot-long boat through the waters of the Alameda-Oakland Estuary (2400 Mariner Square Dr., Alameda). But the Alameda Dragon Flyers -- a part-recreational, part-competitive band of paddlers -- gives you the chance each Saturday with free introductions to the two-thousand-year-old Chinese sport of dragon boating. The weekly sessions are open to athletes of all abilities, and the first three are free -- after that, participants are asked to join the California Dragon Boat Association for a $50-$120 annual fee. 8:45-10:15 a.m. 510-521-7555 or AlamedaDragonFlyers.com
