1. What is the category?Commercial and domestic food service technology
2. What is the key principle?Thermodynamics for maintaining chocolate's liquid state and mechanical transport via Archimedes screw
3. How does a chocolate fountain keep the chocolate flowing?It has a heated basin that stays between 100-120°F (38-49°C) to keep chocolate fluid but not burn it, and special chocolate with a little vegetable oil helps it flow.
4. Why do chocolate fountains use an Archimedes screw?The Archimedes screw lifts the thick chocolate up from the basin to the top of the fountain, then it falls back down in a waterfall. The screw is a simple, ancient device that works well with the heavy chocolate.

Viscosity: A fluid's resistance to flow; how thick or thin a liquid is.
Thermodynamics: The branch of physics dealing with heat and its relation to other forms of energy.
Archimedes Screw: An ancient device used for raising water or other materials, adapted here for moving viscous liquids.
