A wire maze is part of an open electrical circuit that closes when a metal object touches one of the wires, as it does in the classic children's game of "Operation." in which the nose lights when a player touches the metal body sides with the metal tweezers. A good household example of a closed circuit is a light bulb. The circuit is open until the switch is turned or flipped, thus closing the circuit and lighting the bulb. You can make your own wire maze that causes a buzzer to buzz or a light to illuminate and learn about electrical circuitry in the process.
Cut an eight to 10 inch length of wire and wrap one end around the positive terminal of the battery. This wire provides a way for electrons to travel from the battery. Attach the other end of the wire to the bulb or buzzer.
Attach another length of wire to the other end of the bulb or buzzer. Shape this wire into a maze. For example, you might give it an up-and-down wave shape or a side-to-side shape like a slithering snake.
Cut a third length of wire 20 to 25 inches long and connect it to the negative battery terminal. This provides a way to ground the traveling electrons. Make a small loop 1 inch in diameter out of the end not attached to the battery. The circuit is currently open because the two wires are not joined, and the bulb or buzzer will not be engaged.
Tape down the battery and buzzer or bulb to the board so that your circuit and maze are stable.
Use the loop you formed to travel over the wire maze without engaging the sound or light. Time yourself to see how quickly you can move the loop through the maze. Count only the times when you were successful and did not close the circuit.
