Fire danced across the top of the Rubens’ tube as sound waves of different tones revealed their wave functions. A vortex cannon filled with smoke shot rings far across the room. SPS members smashed fruits and flowers frozen with liquid nitrogen. Balloons dunked in liquid nitrogen flattened as the air inside them cooled, then came back to life, and reinflated when back in the warm air.

This year’s Annual Physics Show at Minnesota State University Moorhead was a great success. Demonstrations drawn from the world of physics taught the students and adults who attended about friction, forces, light, magnetic fields, and sound. Fifteen SPS members participated in the show. They were able to gain experience presenting experiments in front of a crowd and also helped in the advertising, radio interviews, and group activities that led up to the show. Our audience was made up of people from Kindred, Fargo, Moorhead, and other nearby cities. We sparked their imaginations and their interest in the physics that surrounds us all. //
