Standing in the basket of the RE/MAX hot air balloon, pilot Bill Baker demonstrates how the propane burners work to an audience of students at William J. Onahan Elementary School, 6634 W. Raven St. in the Chicago real estate neighborhood of Norwood. The burners are used to heat the air inside the balloon, causing it to rise. The demonstration took place May 26 when the RE/MAX balloon and its crew visited the school to present an educational program.
