Parallel and series circuits
Operation
First, attach the metal rods to the battery by unscrewing the black caps and place the rods around the screws. Then replace the caps. Next, clip one light bulb on the metal rods to show a circuit with a single light bulb. To show series circuits, clip two bulbs together and place the end of each clip on opposite rods. To show parallel circuits, clip each bulb separately to the rods. The bulbs in series will glow less brightly than the bulbs in parallel.
Safety
The ends of the rods pose an eye hazard.

Four light bulbs with clips can be wired in series or parallel circuits using two metal rods attached to a 6V battery.
