My apartment is filled with fluorescent lightbulbs. As we study electricity and how incandescent bulbs work, it is clear that these bulbs are very inefficient. Most of the energy that goes into one of these bulbs comes out as heat that doesn't do anything but burn you. Thus, when our last incandescent bulbs burned out, we decided to get fluorescent ones. Anyways, I was looking for a topic to talk about and got a little thirsty. When I opened my refrigerator, I had a sudden burst of inspiration and looked at the lightbulb that illuminates my fridge. I noticed that it is an incandescent bulb, which surprised me.
It's really bright and thus hard to see but that is definitely an incandescent bulb. The fridge info is just a bonus. I then looked and spotted the switch that turns the bulb on when I open the door.
From our studies into electrical circuits, I'm pretty sure that when I open the door of my refrigerator, a spring pushes this little doodad out, which completes the circuit and turns on the light. When I close the door, this button gets pushed back in and the circuit is broken, turning off the light. Cool.
