There were a total of 103 members in attendance on Saturday May 23, 2015. The members were divided into three groups to attend three different events, “Liquid Nitrogen”, “Heat Shield” and “Tour/Light”. Liquid Nitrogen demonstrated the effects and usages for the substance and kept the members somewhat spellbound with the uniqueness of the substance. The Heat Shield was an experiment to build the most effective heat shield from the materials provided: Aluminum Foil, Canning lid (large), Canning lid (small), paper clip, Popsicle stick, Graham Crackers and a toothpick. The resulted shield would have to hold up for 120 seconds before falling of a wooden dowel that it was glued to. They then had to figure out a formula to find out the “Mass Cost” and the lowest Mass Cost would be the winner of those that lasted the 120 seconds. I never did find out who the winners were but all the cadets did real well. The Tour/Light showed the various types of light and everyone got to check to see how well they could conduct the light energy and light up a fluorescent light tube. Some did real well. Pizza was delivered for the lunch break and it seemed everyone had their fill. Each event took about an hour and there were three classes for each event. It was conclude by about 3:00 PM and all returned home safely. All the Cadets and Senior Members enjoyed the day and the events. The photos are somewhat self explanatory.
