Magic Tricks

After watching the public video of Colin's Royal Variety performance, I thought I already knew what the basic gimmick was here. And yet I was fooled because the people had a much wider free choice than what was on the cards. After rewatching it several times, I was able to reconstruct the clever structure that allowed it to be possible (otherwise I was stuck thinking it had to be pre-show or stooge work, which it is not). That principle alone dramatically elevates the impact.

I still bought it, as felt I should support an artist after studying their performance enough to reconstruct the components. Then getting the instructional video, I found the gimmick was more elaborate and clever than expected and the video includes another section of the performance not recorded anywhere else. That addition enables further impossible hands-off predictions for 3 more audience members. When I saw the extended performance, I recognized the Mentalism principle at play from a classic multi-card prediction routine.
Much credit here to go beyond Predicting a playing card to any random thing someone could think of, combining and layering multiple methods that mutually cancel each other out for a much stronger total effect.
