I heard about this years ago - I think I was in high school - and didn't believe it. I tried it in my home freezer but didn't have the proper equipment to determine when the phase change was complete. What I did find was the hot ice tray melted into the ice on the shelf, resulting in better contact than the cold tray.
Can anyone find documentation of these experiments?
Just in case it would help to do a search, this is called the "Mpemba effect"
