A light bulb has a filament wire inside made of nichrome. When electricity is passed through this wire it lights up brightly. If this happens in air the wire burns out and breaks. To stop this, bulbs are filled with a non flammable gas called argon that allows the wire to glow without breaking because there is no oxygen inside the bulb.
