Show -N A W S- Spanish Fork B6 • WEDNESDAY, OCTOBER 31, 2007 Covering what matters most The science of ice cream Salem Brian Moser SFJH Recently, Jerry Hancock, owner of Subzero Ice Cream in Orem, spent the day at Spanish Fork Junior High making ice cream for about 500 students! He makes ice cream using liquid nitrogen. Having a degree in Chemistry from BYU, he was able to reinforce various core science topics such as: the kinetic theory of matter, changes of state, heat transfer, pressure and density. One very interesting thing that happened was when he put liquid nitrogen in a metal bowl, liquid drops started to condense on the sides, similar to how beads of water form on the surface of a cold soda can or on the mirror in a bathroom. He asked the kids what they thought it was. An overwhelming response was that it was water, but water would have frozen solid at -320 degrees Fahrenheit. The liquid dropping off the bowl was in fact oxygen! It's strange that the very air we breathe can be made to turn liquid. Another thing he did was put a balloon in the liquid nitrogen. It condensed so much that the balloon became as flat as a pancake. When allowed to.warm up from the air at room temperature, it expanded back to its original size. In addition, he shot streams of nitrogen into the air from his pressurized tanks, causing the air in the room to fog up. He mentioned that there was more , Courtesy photo BIG MESSAGE: Salem Elementary created a human NO to drugs in connection with their drug free campaign. Larsen THE WRITE STUFF: The thirdgrade students at Larsen Elementary School are excited about receiving new dictionaries that each student could use at school and at home. The dictionaries were donated by the Rotary Club and Zions Bank of Spanish Fork. Pictured with Kathy Brandon and Ed Christensen are Austin Roundy, Tiana Vakaafi, C J .

When he blew over a bowl of boiling liquid nitrogen, it formed a much more dense cloud, because the water in the air was condensing from the cold. He also put liquid nitrogen into a water bottle, allowing the pressure to build up, until it blew the lid off!Students had a lot of fun seeing real life applications of many of the concepts they learned in the classroom. Jerry Hancock, with his chemistry degree, has found a way to make low-fat ice cream taste like high-fat by causing the water crystals in ice cream to freeze so fast, that they are too small for the tongue to detect. On Jerry Hancock's lab coat, it read: "Subzero Ice Cream: Where Science and Cream Mix." We appreciated the opportunity to collaborate with business in the community and to give our kids a more enjoyable learning experience. Courtesy photos "It's looking like it never hftppeaed." ON THE FARM: On a beautiful warm fall day, Larsen Elementary first graders, enjoyed taking a hayride, looking at animals, getting lost in a corn maze and picking out their very own pumpkin at Hee Haw Farms. First I want to thank Robarge for the concern they have about their customers and their feelings about the work they performed. It is nice nowadays that there are some businesses that take pride in giving genuine service. I was very pleased with the job that they did on our Equinox. It is now like it should be — looking like it never happened. The workmanship of the repair is above reproach. Thanks for a job well done.
