As promised here is my guide to releasing magic products. Will it be informative or amusing? It's a 50/50 shot really.
The first step to releasing a new product into the magic market is: DON'T F$%#!& DO IT! There is already too much rehashed crap out there and it's choking the internet to death.
That product is something very unique in method, prop, or visual. If it's a utility prop that has multiple uses and allows other to create for themselves then by all means go for it.
All of that aside, let's assume you ignored the first few sentences of this post, and are going to release your "brand new" handling of an ace assembly. In today's world it's so easy to create something, film it, and put it online or on a DVD in the SAME DAMN DAY that it's mind wobbling.
The real first step is this: Do some R&D first! (That's Research & Development not Record & Distribute) Go out and see what your effect can do. See if there is a way to clean up the handling, see what effect it has on REAL people, and make sure it hasn't been done before. Youtube and the rest of the internet is NOT the way to gauge how well a magic effect plays. You have to leave your house and actually perform it. (I know, out into the "real world" sorry.)
Only after making sure it's something new (or so old no one can tell you but the people with no lives who can quote you every page of Erdnase verbatim) then you have to decide what medium to put it on. DVD, download, flash drive, morse code? That will be tomorrow's article.
Now get off my lawn...
