John and crew
John has it right. The larger number of polarizers at small angles between
them increases the amount of transmitted light. (However plastic polarizing
material always absorbs some light in addition to its polarizing effect so
to actually see this effect you need to use non-absorbing polarizers such
as nichol prisms.)
