The purpose of this project was to create an efficient, cheap, and eco-friendly hand warmer for San Marin students and staff. There were plenty of steps we took to find the perfect design. First, we had to test all the salts and find the calorimeter constant of hot and cold water. We then had to choose our salt (lithium chloride) and design the hand warmer.
Underneath is our presentation of the perfect hand warmer.

Reflection
I think this project went pretty well, but could have gone better. Two things we did well were the design and the calculations. Two things that went less well were time efficiency and communication. I think we should have started our presentation earlier and do more tests that could have helped with our research. Our group communication wasn't good either, and led to some problems in our presentation.
