Article #10: What does demonstration mean? How should demonstration be done to make it work?

• Demonstration is showing how a thing is done and emphasizing of the salient merits, utility and efficiency of a concept, a method or a process or an attitude.
• In the demonstration of a new product a speaker shows the product and tell all the good things about it to promote in order to convince the audience that the product is worth buying.
• It is best for the expert demonstrator to assume that his audience knows nothing or a little about what he is intending to demonstrate for him to be very thorough, clear and detailed in his demonstration even to a point of facing the risk of being repetitive.
