The heel of the shoe is mechanically connected with the stage, which can firmly fix the body support point. This method overcomes the shortcomings of the rope system and can make the performance go on coherently. So as to achieve the visual effect that the center of gravity of the body exceeds the support point. At the same time, the "grappling hook" system of the stage can be extended and retracted accurately and timely through the control of precision instruments, so as to achieve the purpose of not being discovered.
Extended data:
The illusion of getting rid of gravity is a patent created and applied by Michael Jackson.
At first, Michael Jackson tied a safety belt around his waist to complete this movement, so he often saw the classic 45-degree forward rotation in his MV. Later, in a concert, it was impossible to install and remove the rope tied to his waist, which would also restrict his physical activities, so he decided to invent "anti-gravity shoes".
Jackson and two fashion designers left a hook position at the heel of the special shoes. When he needs to lean forward, a row of hooks will rise on the stage. At this time, the stage will create other visual effects to attract the attention of the audience. Jackson and the dancers will take the opportunity to slide the heel onto the hook and buckle it, and then perform a forward performance.
Of course, even so, it is inseparable from the hard exercise, careful rehearsal and running-in of dancers such as Jackson, as well as strong back muscle and body balance control ability.
