demonstrator
One showing dissent
A demonstrator is someone who demonstrates.
Most often this means a person participating in a public protest or march: Demonstrators gathered outside the courthouse.
It can also mean someone who shows how a product or technique works: a demonstrator at a cosmetics counter.
A demonstrator model is a product used for display or trials, often sold at a discount afterward.
