Jimmy tours a chocolate factory to discover what gives chocolate its glossy shine. Temperature control is vital to prevent it becoming dull and crumbly; the chocolate must be cooked at exactly the right temperature, so the crystals form in a tightly uniform pattern.
This clip could be used to introduce students to mass manufacturing processes in food production. Teachers might use this clip to discuss the role of engineering and science in food manufacture. Students could discuss the reasons why shininess and crunch may make the chocolates seem more attractive to the consumer.
Students could make their own products with chocolate or chocolate icing, and try and achieve a shiny finish as featured in the clip.
