This is my human costume i’m really a potato shirt

Many of us will remember building a potato battery as a science project in grade school. These projects were based on the principle that electricity flows from negatively charged electronics to a positively charged substance. Interestingly, the earth itself is another great example of an organic battery. Earth or telluric current is an electric current that moves underground or through the sea. Currents arise naturally in the earth from the chemical composition of certain minerals as well as temperature differences such as those near volcanoes. Electric currents are generated when a portion of the earth interacts perpendicular to the Earth’s magnetic field.
