Hand Warmer Project
For this project, me and my group were faced with creating a hand warmer. The purpose of the hand warmer was to sell at our upcoming student store, while also teaching us valuable chemistry and lessons about ion destruction.
We were instructed to work with an ionic salt. We decided with a different course of action. We wanted to go a chemical free route due to their cost and the safety issues. Thus, we went through many different brainstorms for our product.
With our designs, we followed a simple theme of unique, chemical free, cost-effective, and liquid free. We began with the idea of a microwavable rice mechanism. We were then told we needed some sorted ionic salt.
We then began experimenting with military technology, such as the one available in MREs. We wanted to face the challenge of getting the chemicals t activate as opposed to the actual chemicals.
When that seemed to be failing, we turned to commercial hand warmers. We looked over the ingredients and decided to start with a list of ingredients influenced by them.
We faced many problems with this design. We were missing two necessary ingredients for a duration of manufacturing. We were missing the vermiculite which was essential for holding water without leakage, and the iron powder which was a major activator. We substitued many things in for the iron powder after finding the vermiculite. We finally obtained the iron powder, and after a few trials, we recieved an almost 80 degree increase! We sewed it up and it was very efficient.
Our presentation went very well, with much positive feedback. The presented slideshow is below.

In my opinion, our hand warmer project went very well. but there are a few things i would have changed.
I would have rather we had more time to perfect our plan, and that we figure out our disadvantages and advantages more.
We manufactured our hand warmer very well, and we worked together well.
I thoroughly enjoyed this project. it did get rocky at times, but we always came out with something or other. I am very happy with the result and everything it took to get there.
