    DIRECTIONS

    1. Connect the negative terminal lead to the foil square marked negative.
    2. Touch the positive terminal lead to square ‘A’, marked positive (current goes the opposite direction through each strip).  The two adjacent foils repel each other.
    3. Touch the positive terminal lead to square ‘B’, the other positive square (current goes the same direction through both strips). The two adjacent foils  attract each other.
