In this video David demonstrates:

• Rapid induction
• Revivification (accessing a previous experience of trance to induce hypnosis)
• Post-hypnotic suggestion ("if you see me touch my right earlobe you'll immediately fall into an hypnotic sleep")
• Post-Hypnotic cues (touching his earlobe and saying "sleep now")

It's worth noting that although this is a light-hearted demonstration along the lines of what a stage hypnotist might do, David's manner remains quiet, and gentle, and respectful. The rapid induction of trance is activating the parasympathetic autonomic nervous system response in the subject. As previously discussed, this is the most comfortable way to rapidly induce trance - with quiet confidence, finding something to immediately grab the attention of your subject. You will see that the lady in this video appears at ease, and comfortable the entire time.
