Physics students float large balloon over CMU campus
Traffic slowed near 11th Street and North Avenue Tuesday afternoon as drivers gazed at a large black balloon floating over Colorado Mesa University.
A long string attached to the balloon was wrapped around the hand of Dirk Terptra, president of the Society of Physics Students.
“That’s a giant solar sausage,” he said while slowly reeling in the solar bag.
Each Tuesday, the club gives some type of science demonstration to their fellow CMU students as a way to attract them to the sciences.
“This one is demonstrating that hot air is lighter than cold air,” Terptra explained.
The club has shown students a wide variety of other physics examples including dropping eggs from the library’s roof, launching a tennis ball cannon, and letting some lie on a bed of nails.
The group is a chapter of the national Society of Physics Students organization. More information is available at http://www.spsnational.org.
