Take two parts science, add one part magic, throw in a large dose of audience participation and you've got Xtreme Science Magic, a show offered at a number of San Jose Public Library branches during the month of March. In this video, children at Willow Glen Library delight in the "smoke-ring blaster" at a performance March 10. The educational and entertaining show will be at six additional locations this month including King, Evergreen, Berryessa, West Valley, Vineland, and Santa Teresa libraries. Details and show times can be found here. All performances are free.
