How can I make a lightbulb?
Ask this dude.
Blow a glass bulg.Insert a tungsten filament and lead wires.Vacuum out the air or fill with argon etc.Seal the bottom and "light it up".
"Blow a glass bulg."You sound angry. lol :)
No, not at all. I just didn't check my typing very well.
Better to fill with argon at some non-trivial pressure. Under vacuum, the filament is more likely to sublimate.
Or helium, I like his reasoning.http://www.periodictable.com/PopSci/2005/12/1/index.html
You could do this using a lab beaker, rubber stopper etc.
Do you just want to experiment, need a special light bulb or imagine you can save a load by making your own.Youtube has several videos of how they are made.
