Scene 2: Shows the Diviner from the participants’ point of view.
Scene 3: Close-up of the diviner.
Scene 4: Participants make a wish with their eyes closed.
Scene 5: The diviner’s hands are hovering above the crystal ball.
Scene 6: Energy flows into the crystal ball. The astrological element transitions to a starry night sky background or a mystical scene with candles, runes and tarot cards.
Scene 7: The crystal ball glows.
Scene 8: The participant looks into the crystal ball with fascination.
I can not comment on your google doc so I leave comment here. Have you considered about infrared sensor because heat sensors maybe are not sensitive enough.
