Models may specialize in modeling one part of the body, such as hands, legs, or face. Some models appear in television ads. Fashion models display clothing before an audience. They stand, turn, and walk to demonstrate a garment's features. Artists' models pose for artists and sculptors.
Some workers demonstrate new products and services at exhibits and sales meetings.
These workers are called product demonstrators. Unlike most models, product demonstrators talk to customers. They attempt to persuade people to buy their products. They may give out product samples. They may collect names of potential customers.
