Physics professors Sidney Nagel (top, left) and Heinrich Jaeger set up the final science demonstration at the recent event Science with a Bang! The two physicists safely prepared the experiment to propel a large trash can to the ceiling with an exploding liquid nitrogen-filled soda bottle. The second annual Physics with a Bang! Holiday Lecture and Open House, provided a fun-filled day of demonstrations, lively lectures and informative discussions for adults and children. At right, Imogen Foster (left) and Ilana Dutton enjoy the show.
