Asking questions of the audience while making a presentation is a strong way to keep them invested in what you have to say. There are 3 types of questions that are particularly useful:
–Polling questions. Show of hands. How many of you believe we can move humans through space safely at enormous speeds? Follow the question with a comment about the polling results and implications.
-“What if” questions help the audience envision things that may not exist. What if there could be a way to move people from one coast to the other in 40 minutes, would you be interested? Pause after asking the question and then a reveal the answer.
–Rhetorical questions puts the audience in your corner. Do you know that right before every break-through invention, most people believe it can’t happen?
