Demonstrative speaking is a way of explaining how something works. First you need to know how something actually works yourself by going through the process. It is kind of like putting together some IKEA furniture. Always make it concise. Take complex information and make that information simple and accessible for the viewer.
When you have a live audience, you do not have the advantage of being able to start and stop the recording. When speaking demonstratively you must go from beginning to the end of the process. If you have problems putting something together, focus on how you resolved those problems. This way your experience becomes useful to the audience.
