One thing I’ve realized as I’m out there talking more and more about the vanishing birdcage is how many magicians have never actually seen it done live. Many have seen it on an old video of Blackstone, but not live. At a virtual magic lecture someone asked me about my Take Up Reel that I used with a vanishing birdcage, so I gave a quick talk about it.
I think most magicians dismiss the cage as they think it’s much simpler than it actually is. There’s a lot more to doing it consistently than simply pushing your arms forward. However when they see it done in real time they realize how amazing the trick is!
