The lights will be out, but the fun will be on when Batavia celebrates Earth Hour Saturday night.
Organizers have added music to the city's annual observance of the global event organized by the World Wide Fund for Nature.
People are asked to turn off their lights from 8:30 to 9:30 p.m. to show awareness about environmental issues.
The celebration is 7 to 9:30 p.m. at the East Side Community Center at Van Buren and Wilson streets.
There will be games, bilingual storytelling, candlelit yoga, and massages.
Visitors can try a crystal light bed and gong bath meditation. There will also be a drum circle.
There will be demonstrations of how to make personal-care items, and a talk about animal totems.
The Fox Valley Astronomical Society will set up telescopes, and there will be "paint with light" portraits taken.
The band City Hall Fred Lite will play acoustic music.
The event is organized locally by the Batavia Environmental Commission and the Batavia Park District.
The City of Aurora is also encouraging people to participate in Earth Hour and wants them to collect photographs of how they spent the hour. Photographs can be emailed to MyAurora@aurora-il.org.
