Hand Warmer Project
Project Description:
This project called for some creativity to create a product that would help keep outdoor winter sports players' hands warm with a cost efficient hand warmer. We were able to use our knowledge of chemicals and how they react to choose from different salts, we conducted a series of trials to see which salts reacted best together to create a reaction that would produce heat quickly. From all of our trials we concluded that most efficient products we would use were 50 ML of water and 10 grams of calcium chloride. We decided that this would be the best choice because it's a lot more cheaper than the other option lithium chloride, and even though calcium chloride can potentially be a tad more harmful than the lithium chloride that's only if there are large quantities, but in our case we are only using 10 grams which wouldn't be harmful.

Reflection:
With our group we started off really well, we were making sure to test all the different salts and which one would have the highest heat increase using the least amount of product to become the most efficient. We also generated a lot of good ideas on how we would be able to put all these ideas into a usable product for San Marin sports fans and players at an efficient cost. We came up with the idea that we would put a small water ballon filled with our salt inside a slightly larger water ballon which we would fill with water. Then inside of the smaller ballon we would put the end of a paper clip that would be sharp enough to pop it so the salts and the water would react. We defiantly could have improved on a few things because during our presentation to our teacher, the whole ballon pooped on her including all of the water. This means that we could have maybe thought of some more alternative methods to pop the smaller ballon that was inside with a lesser, not as sharp item that wouldn't result in the popping of the entire ballon.
