Hand Warmer Challenge
In this project, our group created a hand warmer design that was efficient, cheap and easily mass producible. We started off by testing our salts. As seen in the chart below, Lithium Chloride had the most ideal temperature change. Once we found our salt we then began the design process. We first decided to melt the edges of that hand warmers together but that did not work as well. Then, we got a heat sealer and that work much better than the melting process. We then planned how to place our bags of salt in our 15 mL of water. Then we made our design plans. We planned to produce three different sizes of hand warmers to accommodate our San Marin student population.
Reflection:
This project was very fun. The fact that we got to design our process and product from the ground up really intrigued my group and I. We worked together very well and agreed on all ideas that came to the table. We did very well with creating a simple design and executing our vision for it. We were not very efficient with our time and in the end we struggled to keep our project together. A T.A. ended up throwing away all of our products in the end so we did not get to demonstrate our design to its full potential. Overall this project was very fun and I hope to work with the same people again in the future.
