Solar powered: YMCA Summer Day Camp students feel the hot surface of a floating 50-foot-long solar bag during the Girl Scouts Summer Science program Tuesday in Riverfront Park. The bag was made of black plastic that absorbed solar energy. The air in the bag warmed, causing it to lift. The scout camp runs through Thursday.
