Have you seen the sidewalk artists who use amazing techniques to paint surreal landscapes with spray paint? It's entertaining just to watch as they apply different colors with various tools and props.
The same thing happens when a business attraction is being built. It will entertain your organization for weeks as it comes together, and towards the end of the built, the excitement is heightened as finished touches are applied behind a screen. Just like home improvement shows where homeowners participate up to a point and then wait for the big reveal, we balance participation with anticipation in our process. That's entertainment!
