Don't try this at home
This chapter, we are learning about electrons jumping from one object to another. We excess charge can occur if an object isn't grounded. In the case of an outlet, when the outlet gives electricity to the plug of an object and the plug is taken out while the outlet is still giving electricity, an excess charge is created. Some plugs have a third prong which grounds the plug, neutralizing the excess charge. Most conventional, lower powered household items don't have the third prong, therefore the excess charge will form. in this video, my iron is plugged into the wall. As electricity flows through it, I pull out the plug, creating a visible excess charge of electrons in the form of a spark. I performed this in the dark so it would be easier to see the electrons jumping from the wall to the plug. Here is also a picture of what the outlet looks like in the light.
