Effect of % Oil on Freezing Point
Thermocouple resolution is only precise to 1°F and readings varied greatly depending on where in the mixture temperature was measured. Luckily, a linear approximation seems to be appropriate as there should be no physical reason for higher order behavior.

Main Project
To design and build an improved demonstration device to more clearly show that a phase change material can accomplish work.

Takeaways
- Things almost never go right the first time.
- Having curiosity and a willingness to ask questions is the quickest
way to learn.
- Work does not have to be the dull grind it is often made out to be.
