Dancing on the walls

        These guys have really gone way more pro. Year after year I studied the motion of a brick or a book on the incline but watching this video really made me appreciate the application of this concept to create something so magical and pleasing to watch.
         When the person is attached with the rope at an incline, the tension in the rope can be split into two components; one which balances the weight acting vertically downward and another component pushes him/her to be stuck to the wall. Now here's the beauty- The major part of tension is nullified by the weight acting vertically downwards which implies that only a small part keeps him pressed against the wall.
         The person needs only a small force to push against the wall to jump in air making this situation astonishingly similar to dancing on moon where the gravitational pull is a sixth that on the earth. Although the forces of his weight and vertical component of tension cancel out, they are sure to cause heavy stresses in the person's body which he has to sustain while simultaneously dancing; kudos to him on practising this stunt and mastering it to this extent.
