For centuries street performers have been using demonstration as a successful way to prospect for a new Coeur d’Alene business. A street performer who juggles sets up in a busy park and begins to juggle bowling balls (demonstration). Soon people start to take notice and crowd around to watch (prospects). Some people leave while others stay to watch (qualifying). The performer continues to demonstrate juggling skills to an amazed audience (presentation). The juggler completes the presentation and takes a bow as people drop loose change into a box (closing. Doing no more than demonstrating a service (entertainment), the juggler has attracted prospects, qualified some. presented to a crowd and closed a few sales.  The complete sales cycle, all in a matter of minutes. 

This leads me to this point: 

Most products and services can be demonstrated in public for prospecting purposes beyond what we consider as acceptable demonstration forums of trade shows and seminars. For instance, if your CDA business sold fishing poles and went to a crowded beach on the weekend and cast a line it would not take long before people approached you and asked if the fish were biting. Or your Idaho business operated a martial arts training facility and took the class to a local park for a training session, once again it would not be long until a crowd gathered and questioned about your school ensued.
