Super Awesome Pencil and Electricity Experiment


imgur

This GIF is of a pencil that connects to a ten volts direct current battery. It flows electric current through a 0.5 mm lead pencil. The experiment shows what happens when electricity passes through a substance with low conductivity. Energy from the electrons dissipates in terms of collisions.  The filament quickly reacts with atmospheric oxygen and erodes the pencil. The end product of this volatilization is carbon dioxide and ashes.
