freezing a qcam :)

some time ago someone from .ca (if i remember well) asked
how the qcam behaved in extreme temperature conditions.
To this person (or any other who did similar tests) :
i wanna make an accelerated movie of the explosion of a glass
bottle under the pressure of freezing water. Did u try 
using the qcam below 0 celsius degree ? did it still work 
correctly afterwards, or did u see more dead pixels (dead = 
saturated or permanently black) as expected by cooling the qcam 
too quickly.
Oups forgot, in all this post qcam = b/w qcam
