That is exactly what I'm saying. That trick was published by Paul Curry in like 1942 and his handling is still one of the best out there. The only ones I put anywhere near it are Paul Harris' (Art of Astonishment) and Jon Armstrong's. I don't know if Armstrong has published his version in a book or anything, but I learned it in Season 1 of Reel Magic Magazine.
There are other versions and some of them very good - these are simply the ones I prefer.
You said:
but if you want to learn in a non-professional way (as I do) videos are the best source so far right now.
Which is just wrong. Video is not the best source, it is simply a source. Furthermore, it's a source that tends to perpetuate a lack of originality in magic performance. I remember an interview with Daniel Garcia where he commented on how often people tended to copy his performances on the DVD word-for-word, even when he was making up the words on the fly. But people who are learning by watching tend to mimic. The good ones then go beyond that and develop the presentation themselves, but most magicians are, I'm sorry to say, not good.
Books have the tendency for someone to understand the trick on a deeper level than video. This is because you have to understand how the trick works before you can even start practicing it, rather than just mimicking the guy on the screen. They also tend to be pretty scant on the presentation, so the performer is more or less forced to come up with one.
They both have their place. Videos do help clarify certain things, like finger positions and actions which can be lengthy to describe in text but executed in seconds. But to say videos are the best place to learn is just wrong.
Furthermore - You mentioned YouTube. YouTube is a cesspool of terrible magicians. There are gems to be found, but for the most part, the overwhelming majority of the videos on YouTube are perfect examples of how NOT to perform magic. Yes, you may actually learn the moves but in all likelihood that is the best you can expect from YouTube. You will get no theory - because these people don't think about theory. You will get no tips from experience - because these people have no experience. They are just repeating what some other exposer showed them, they haven't refined the techniques in live performance. If they were out doing live performances they wouldn't be resorting to YouTube. If they were any good at performing, they wouldn't have to expose other people's tricks to get attention.
And even further, when you learn tricks from YouTube, excluding public domain stuff and stuff that is legitimately given away by the creators, you are aiding in the theft of intellectual property. Ever wanted a magic product but it was just too expensive so you found an exposure of it on YouTube? Congrats, you're part of the reason it's so expensive in the first place. Creators are increasingly refusing to share their good material in a mass market way. I've stumbled upon more and more people who will only sell directly. They print small runs of their products and they vet their customers before selling the product. This is specifically to cut down on the exposure. People don't give away things they actually value, and if they have to work for it, or sacrifice their time, or if it gives them some level of prestige to own it, they value it and they won't give it away.
So to recap, because the YouTube generation has a very short attention span - YouTube is a place to learn bad magic. If you want to learn good magic - read books.
