Today we learned about electrons. An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom. Electrons can provide light. When the light is turned on, they go through wires to get to the place they want to go. Little do the electrons know they are about to go into the lightbulb and provide light. But when the light switch is turned off, the process discontinues  when liquid gets in the process, it messes the whole thing up, because the electrons go into the liquid and messes up the process.
