Transcript of Hot Potato!!
BY: David PendletonAnd Timothy Pickett
PURPOSE•Compare lunch bag materials by experimentallymeasuring the transient temperature response of a potato and comparing it with an analytical model
We used two types of bags:PolyvinylChloride and Polyurethane

CONCLUSIONCONCLUSION
• The bigger the bag, the betterThe bigger the bag, the better
• Urethane maintains food temperature Urethane maintains food temperature longerlonger
