Guy Makes a Light Bulb from Pencil Lead..Very Neat

This home scientist shows how to make a light bulb from pencil lead.  Safety is the number one priority as stated by “Crazy Russian Hacker” the gentleman in the video.  Anyways, this is just fun.  Why do light bulb companies get to make so much money I mean the filament always burns out right?  What if we could make long lasting light bulbs at home?  Well not sure if this one would be less expensive than a regular light bulb haha but its very cool.
