This exercise experiments with the different ways to close a circuit, any material could be a switch with the right construction with more visually interesting results than the black boxes in our daily electronic objects. In this case, a candle is used to warm the air around a metallic spiral and produce movement. When the spiral moves, it opens and closes the circuit, touching aluminum leafs installed inside of the small greenhouse. When the switch is on the little flag in the motor moves and the lights turn on. | |||
