If was able to build this i would built several,call TV and give them working to them, and many other people.
And i would explain how to build it.
I think this has something to do with this (You will like it) :

Yes i like it.
So... you are suspicious about m.motor from the link i posted?
Yes i agree....could be done more transparent. It is possible to incorporate some fast motor inside plastic rotor and by some hidden switch to start it during video shooting. This could be done. But question is why? Why to involve such effort? For what? To make funny video and fool people arround? I dont know, i am not sure.
What else we can do but to collect material and build same thing and test it? I am preparing material and i will build it soon. Problem are those neodiyum magnets. I have to order them from abroad. Those are not expensive. I calculated; it will cost approx. 15 euros...not a big deal...
