Double-exposing Polaroids?

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

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,

There exist Polaroid backs for some top-end film cameras like Hassies and
Rolleis.....I see no reason why you couldn't double expose those just as you
can with normal film.......
