We've grown up seeing this dance move, but little did I know that this dance move is patented.
[ Method and means for creating anti-gravity illusion Michael J. Jackson et al ]. Whacko-Jacko also has a patent to his name and a nice one!
I thought of it as some clever camera move and later editing the video, but it is not the case.
From what I understood, Michael Jackson and other people had come up with the idea of attaching the shoe to the dance floor and then balancing even though the center of gravity does not permit. Looks like the shoe's heel is fixed to the floor, through some nails.
