Need help please!!!
 
How would I hook a light bulb filament to some sort of electrical wires? and What kind of power supply would I use to run that?

a light bulb filament has to be in a vacuum ( the glass sphere when you buy it) for it to run for very long without catching on fire and disintegrating.

Thats right as the temperature the filament reaches is so intense that it can burn.
