Holi at Solar One

This solar-powered, ecologically minded center on the East River holds a free, family-friendly paint-throwing party to mark the the Hindu spring festival of Holi. If you're heading to the fete after work, make sure you ditch the suit; the colors may (as in, probably will) stain clothes, but at least you can be confident the powder's not toxic—Solar One made their own from rice flour and food coloring.
