Double-exposing Polaroids?

I realize this is a 35mm group, but figure you folks might have

Is there a way to double-expose a Polaroid image?

I would imagine if you could snap a Polaroid picture and then somehow
stop it from being ejected from the camera, or perhaps halting the
developing process and then re-loading it into the camera, you might
be able to double-expose it.

Alternatively, is there another way to simulate double-exposure on
polaroids? Ie, to get some kind of image onto the polaroid, even a
smear of luminescent color, before the image is exposed?

Note that I am not a photographer, but rather a teacher looking to do
a demosntration for a class.

Thanks so much in advance,


If you rent or borrow a medium format film camera (any Hasselblad, any
Bronica, Pentax 645, Contax 645 etc.) with an accessory Polaroid back,
you can make as many exposures as you wish on the Polaroid film. A
local professional photographer may be able to help you by loaning you
the equipment.

[Polaroid backs were/are used to make test images to check lighting
and/or composition prior to making the final shot on film. The
Polaroid back is quickly interchangeable with the camera's normal 120
rollfilm back.]
