1.new entertainment and/or advertising article, characterized by being integrated by a bimetallic disc, formed in spherical cap, of the type of abrupt rupture, that is to say that it changes, inverting at a high speed its convexity when exceeding a certain thermal threshold, achieving said effect in this case, by the conjunction of a normal pressure on the cap of the element (as a main factor), together with the influence of the temperature of the human body, so that by holding the aforementioned element, for example, between the fingers of the hand and exerting a perpendicular pressure on the surface of the same, the pair of components, effort plus temperature of the hand, is able to obtain a sudden inversion of the curved-concave configuration of the element, which will recover its shape to be deposited next on any surface or plane, with its concavity directed towards it, at a temperature that has been adjusted in the manufacturing process, maximum at room temperature, causing the said sudden change, a jump of the element, this disc optionally being provided on one or both of its free faces, with a carrier sheet of graphic or word-like motifs, of various kinds, in particular of a nature advertising, firmly attached by gluing or other conventional system, to the external surface of the faces of the disc affected by said attachment, possibly replaced by a coating of brightly colored paint. 2.new entertainment and/or advertising article.
