World fairs present new architecture and design ideas to the public. New technology is a huge part of world fairs. They also bring new furniture, and lighting ideas. New furniture also means new materials. In the Great Exhibition of 1851, the crystal palace is a good example of new technology and materials being incorporated into design. This place used iron and glass which allowed natural light to come in. Designers then can incorporate these new ideas into their own design. The New York worlds fair of 1964, produced a unique experience for viewers. It was called "Peace Through Understanding". Users felt as though they were in a futuristic place with the different things that were found at the fair.
