Make the most of the moment. Wake them up slowly, and have some fun with them before they become fully conscious. Take someone along to help. One of you can interview, and the other can work the camera. Don't let the cat out of the bag.
Surprise is essential.
Show the interviews at your morning or evening meeting. Then blindfold a volunteer who must walk across the room without breaking any eggs. However, before the blindfolded player begins, have helpers silently replace all the eggs with unshelled peanuts. Then watch the fun. The game leader and mind reader are accomplices who know in advance how the game is played and what the code or trick is.
