Hi. this is my first project ever uploaded on net.In this instructable, I am gonna tell you how how to make your own  light bulb.

Step 1: Stuff needed.

1]Pencil lead 0.5 mm.
2]Alligator wires.
3]D sized batteries 8pcs.
4]Glass jar.
5]Duct tape.
6]Cardboard pipe.

This is awesome, experiments like this are often ignored as the technicalities of making it better overshadow the basics, i.e. using a vacuum system to remove or exchange the atmosphere in the jar to allow a longer burn time.
Yes you're right.someone even suggested me using a vacuum pump.
They do it here as well. &nbsp; &nbsp;<a href="http://www.youtube.com/watch?v=pjHcx7YVonE" rel="nofollow">http://www.youtube.com/watch?v=pjHcx7YVonE</a>&nbsp; &nbsp;
