I agree that Do As I Do gets good reactions, I did it for my father-in-law, who sat there looking at me then said “Do that again!”.
One recently that has received some very good reactions for me has been Switch Craft.
The best reaction I’ve had has been from my Dad, when I got him to take a card, then asked him to think of it, and I took a picture of him thinking of the card with my mobile phone’s camera.
“What are you going to do,” he scoffed, “show me a photo of my card?”
When I did he was speechless for five seconds (a long time for my Dad!). “That’s impossible!”
A very gratifying reaction.
