This video shows you how to make a graphite light bulb similar to the one Edison made. Instead of using a vacuum pump to remove the oxygen gas we replaced it with a less reactive gas much like a modern light bulb.
CAUTION: Be careful not to let the wires connect without the graphite in between them because this will create a short circuit and cause the batteries to become extremely hot and could lead to injury.
