Yesterday in tech we made a circuit with a battery that lights up the light bulb. There was a battery with 2 wires which one attached to the light bulb and the other connected to the switch. If you flip the switch it turns on because there are two screws that you put the wires under and tighten the screw which pins the wires down. I completed my circuit after like 15 minutes. It was a great experience and I am lucky that I didn’t start a fire.
