Tomorrow we are going to freeze some New55. The general consensus is that it is alright to freeze old T55 as long as there is enough time afterward for the pod to warm up completely. I have never confirmed this so we will also freeze a couple of old T55 pods.
If you have any real life experience with frozen polaroids, now would be the time to tell us about it. Also if you have been a contributor to New55 and would like to update your mailing address, please do. Send an email with your address to bob at soundwaveresearch.com
