If you're new to analog photography or double exposure, this gives a good overview of the principle
and functionality. However, it only mentions one setup for one photo. The preparation requires a lot
of staging. There are much easier ways, and you can do much more with a Polaroid than the
instructions explain. If you like to experiment and tinker (and this is what you have to do, there
is no way around), you have a great tool and a great giveaway for Halloween; but it's expensive.
