The invention relates to amusement attraction engineering and can be used in teaching physics, chemistry, and biology to demonstrate the conversion of chemical energy into electrical energy. The inventive attraction comprises playing members (1) and (2) of a certain shape whose function is fulfilled by different metals spaced not less than at 0.5 V in an electrochemical series. The playing members (1) and (2) are coupled to visual display means, for instance a microammeter (3). The playing members (1) and (2) are not coupled directly to each other in a circuit. One person (4) is or a group of persons (4, 5, 6) are coupled to the circuit at the opposite side of the playing members (1) and (2) in order to close the circuit loop, said persons being able to interact with the playing members (1) and (2) and between each other by exposed portions of their bodies, for instance by hands. When interaction with a moist medium of skin takes place, there are potential-determining reactions in different metals that stimulate the occurrence of the electromotive force and the generation of circuit in the circuit, which visually, divertingly and amusingly represents the conversion of chemical energy into electrical energy. The microammeter (3) fixes the presence and value of said current.

Abstract:
Collapsible structures may be formed from planar solids. The structures may be comprised of multiple planar objects hingedly connected, where each planar object may include magnetic materials (e.g., magnets, ferromagnetic metals) or electromagnetic materials. Using the magnetic or electromagnetic materials, the connected planar objects may be arranged as a single planar object with multiple layers, or may be arranged as a three-dimensional (3-D) object, where the magnetic or electromagnetic materials may be used to retain the formed 3-D object shape. Application of a current to the electromagnetic materials may cause the collapsible structure to form the 3-D object, and removal of the electric current may cause the collapsible structure to revert to a single planar object. Multiple structures may be combined to form larger structures.
