The Problem • Coffee tastes better hot • Coffee cools rapidly • Insulating a coffee cup costs – Money – Time – Resources
The Process • Sealing the base • Insulating the sides – Corrugated cardboard – Dense cardboard maché • Building the lid
The Solution • Functional Coffee Insulating Device – Low cost – Small carbon footprint – Efficient insulator
The Results Insulation Efficiency 75 70 Coffee Temperature Inside Insulated Cup 65 Temperature (°C) 60 Outside Temperature of 55 Insulated Coffee Cup 50 45 Coffee Temperature Inside Uninsulated Cup (Control) 40 35 Outside Temperature of 30 Uninsulated Coffee Cup (Control) 0 10 20 30 40 50 60 70 Time
