FIELD: teaching amusing attractions designed for teaching physics chemistry, biology with possibility of demonstrating action of electric current of skin-galvanic origin.
SUBSTANCE: two different type metals are in the form of game members and they are connected with unit for displaying electric current. Game members provide generation of electric current in circuit of attraction when said circuit is closed at least by means of one human being that may be in contact with game members through exposed surface parts of its body. Game members are made of metals spaced one from other in electrochemical voltage row at least by 0.5 V.
EFFECT: enhanced efficiency of teaching.
