I keep seeing all of these magicians on fool us and AGT and on youtube in general performing their own created magic tricks, stage or close up and i'm just wondering how they know what materials to use to build their trick. like is there a book or lecture explaining different types of materials or objects you could use to pull off a certain trick like levitating something. I know there's books and pdfs explaining secrets of stage illusions and different false bases, but if there is a source explaining materials and methods for none box illusions and if you could share it that would be great.
