I don't have the JM Craft cage , but out of curiosity I looked it up. So to sell it JM Craft makes a promo video which is posted openly on the internet which exposes the workings of the cage to anyone who happens to see it on YouTube ? REALLY ??? Is this really necessary ? How about just a straight-up performance of the trick with a note at the end about "serious buyers please inquire for details" (then a video demonstrating the details of the apparatus could be sent to any magician making a serious inquiry about purchasing the apparatus). Real magicians know who Tommy Wonder is and if the apparatus is being promoted as a "Tommy Wonder birdcage" they understand what is being sold. No reason to show off by posting a video like this which is not exclusive to magicians. This is a bad trend (laying bare all the details in videos posted on YouTube). Would any of us want some smart aleck kid googling this on his phone after we perform it and sharing the video with everyone around him ? They want a magician to spend $1195.00 for this , but then they devalue the trick by exposing the details of the apparatus in their promo video showing off

I haven't seen a magic shop expose a prop before, odd.

the good news is hardly anyone has seen it, (316 as I write this.)
and due to the title it doesn't rank very high on a search.
the video is also terrible.

The bad news is that the first ranked video is an exposure too,
The upside is that It's even worse than this one.

Didn’t the movie “The Prestige” expose it already?

@David Todd, that's about the magic dealer website and not the consumer base. The video is still there - so maybe a direct note to them would get what you suggested in place?

The internet exposure discussion has been going on here for a couple of decades. We even had someone from the Wikipedia committee visit.
BTW: https://en.wikipedia.org/wiki/Vanishing_bird_cage

Magic exposure is just something that is exceedingly difficult to avoid nowadays with the internet and social media. Wish we had neuralizers from Men In Black to wipe memories before performing tricks to them. Just my two cents

Well I think his point is that it's bad enough when callous fools expose magic secrets on the internet, but worse when it is done by the magic manufacturers/dealers themselves , with no thought given to how in their zeal to sell their wares they are downgrading the value of the magic apparatus they wish to sell to their customers. The magic shops are supposed to be on "our" side , I hope , yes ? But it seems that many do not care for the art of magic , they are only about the selling. This is nothing new in some ways, but at least magic shops at one time had a pretense of keeping the secrets exclusive for magicians who had paid for the privilege.

I really love Tommy Wonder's video on the effect and how to build the gimmick. At the same time, as others have noted, it's been exposed before. What made Tommy's video amazing however was in his performance of it. Everyone there of course knew about the gimmick; yet the performance was astonishing. Right before their eyes just inches away. And if we can suspend our knowledge of it just for a second, we can admit we were "fooled".

Yet it does bother me when certain secrets and gimmicks are revealed. (I still believe in the "magician's code").

But what's really nice is when you fool someone, who thinks you used a gimmick! Lynn

There is also total exposure of Tommy's Ring, Watch, Wallet props, and handling on YouTube with the reasoning being improvements made in the props and handling. A search of 'Magic' & 'Wonder' might expose this higher-level secrecy. Showing off your "improvements" is not a reason to tell the world the secret; not to mention one that is not yours to expose.

Absolutely not yours to expose being the salient point!
