As if David Copperfield had an idea to make the Statue of Liberty disappear. He has a plan he thinks will work, but it doesn’t. So instead, the audience is made entirely of stooges. And we’re made to believe that they’re all random people.
Or it works, and he can actually put random people for whom the illusion will work!
Either way it only really works on TV if you believe that the live audience is real. If it’s a fake audience, anyone can do it, and it’s not interesting. (there are many well known magicians who use stooges and/or camera tricks all the time)
I feel the same here. The very reason people liked the video was the process he presented, not just the result. So lying about it is lame.
And I think it's unfortunate because he could have posted almost the same video with just saying "and… it didn't quite work! So I edited my real yarn logos and threads to get the final clip" and it would still be a cool result.
