A company called Sub Zero Ice Cream offers an educational opportunity for students all around the United States.
Chad Ostler, franchise owner for the SubZero stores located in Cedar City and St. George, Utah, reached out to the White Pine County School District to offer an educational opportunity for the schools in the district.
Sub Zero uses liquid nitrogen to flash freeze ice cream. They demonstrated to the students the use of cryogenic gas, phase changes, heat transfer, inversions, ideal gas law, atmospheric composition, and gas expansion, applied in an everyday situation. In other words, science in action.
Stotler said, “We show them that science is fun and practical in an exciting science demonstration.”
The cost for the 55 minute demo was minimal, at $2.50 per student, and at the end of the demonstration, students received ice cream and a book mark with a reading log.
Tracy Garcia, Sign Language Interpreter explained how KGHM sponsored the event for the students.
“We greatly appreciate KGHM’s generosity and support for our schools,” she said
SubZero was created in 2008 by owners Jerry and Naomi Hancock. With backgrounds in chemistry, Jerry Hancock worked to develop a method to freeze ice cream using liquid nitrogen.
They received their patent in 2014. They were featured on Shark Tank, and although they did not get a shark to invest, they went from two corporate stores, and 18 franchises to more than 50 to date.
The students at Norman Elementary learned some fun facts about nitrogen; it is non-toxic, odorless, tasteless and colorless, and makes up 3 percent of your body weight.
Ice creams are customizable, no wait time, no freezer requirements, and no ice crystals.
Mrs. Walker’s 4th grade class, Mrs. Johnson’s Mrs. Kuehnert’s and Mrs. Crosby’s 2nd grade classes at DEN enjoyed the demonstration.
Other schools that participated were the White Pine Middle Schoo, in addition to the Lund and McGill Elementary schools.
Garcia noted some of the students comments were anywhere from how much they loved it, to how yummy the ice cream was, to how much they enjoyed the science part of it.
Ostler conducted an experiment with gummy bears.
“What happens when we put them in the fridge?” he said. “Do they get hard?
Several of the students exclaimed, “Yes.”
Ostler said, “What happens if we put them in with nitrogen? Will they get hard enough to break?”
The kids cheered on, exclaiming “yes.”
“Is that your hypothesis?” Ostler asked.
He then filled a bowl with gummy bears, and nitrogen, as he walked around the room showing the students the bowl. “What’s happening?”
Several students commented that it was boiling. Ostler poured the gummy bears into a cup and the candy began breaking up and shrinking. The children cheered on, in awe of the science experiment before their eyes.
After several scientific experiments with the students, Ostler demonstrated how ice cream was made and the students sampled the sweet experiment.
Kids licked their spoons, giggled and laughed while they enjoyed their ice cream.
