If you pause for a moment to think about how a light bulb works, then
you'll realize that the filament has to be in contact with the base in
order for the electricity to light it.  For example:
 
A) Bulb: Soft glass is generally used. Hard glass is used for some lamps to
withstand higher bulb temperatures and for added protection against bulb
breakage due to moisture. Bulbs are made in various shapes and finishes.
B) Filament: The filament material is generally tungsten. The filament may
be a straight wire, a coil or a coiled-coil.
C) Lead-In Wires: Made of copper from base to stem press and nickel-plated
copper or nickel from stem press to filament, they carry the current to the
filament.
D) Tie Wires: Molybdenum wires support lead-in wires.
E) Stem Press: The lead-in wires in the glass have an air tight seal here
and are made of a nickel-iron alloy core and a copper sleeve (Dumet wire)
to assure about the same coefficient of expansion as the glass.
F) Exhaust Tubes: Air is exhausted out of and inert gases are introduced
into the bulb through this tube during manufacturing. The tube, which
originally projects beyond the bulb, is then sealed off short enough to be
capped by the base.
G) Base: This is where electrical contact is made. One lead-in wire is
soldered to the center contact and the other soldered or welded to the
upper rim of the base shell. Made of brass or aluminum.
H) Gas: A mixture of nitrogen and argon is used in most lamps 40 watts and
over. Gas slows down the evaporation of the filament.
I) Support Wires: Molybdenum wires support the filament.
J) Button: Glass is heated during manufacturing and support and tie wires
placed in it.
K) Button Rod: Glass rod supports the button.
L) Heat Deflector: Used in higher wattage general service lamps and other
types when needed to reduce circulation of hot gasses into neck of bulb.
M) Fuse: Protects the lamp and circuit by blowing if the filament arcs.
 
One can assume that when making a firebomb out of an ordinary light bulb,
some air will be trapped inside, adding to the ignition.
 
Remember, however, THIS IS ONLY A MOVIE!
