Pershing Students Participate in Liquid Nitrogen Demonstrations

December 26, 2012

Mr. Times, a father from Mrs. Salinas’ classroom, came during 3rd period science class to perform several liquid nitrogen demonstrations on Friday, Dec. 21.

His demonstrations included making strawberry ice-cream in 5 minutes, freezing a carnation flower in less than one minute, and demonstrating how oxygen in a balloon shrinks when exposed to liquid nitrogen, then returns to its original size when removed from the liquid nitrogen.

The students answered and asked questions and ate ice-cream.
