Abstract: 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.
