Today in class we learned how you can light batteries on fire. You can do this if you have a wire coming from one side of the battery straight to the other side. What happens is it gets really fast really quickly. The way to stop this is by putting a lightbulb in between the wires. The light bulbs attracts the electrons in the battery with its copper. The other things in a battery are zinc. The zinc being left behind becomes positive rather than just staying neutral.
