This is a tad weird which has made me wonder how the hell this happened. I got some ice cubes out of the freezer that I made a few days ago, and theres these inch long spikes of ice coming out of the cube. Pics of the ice tray. Now this is interesting, as there was nothing on top of the ice trays and they were placed on the top shelf of the freezer. If someone has any ideas on how these were created, I'd love to hear it :) Update: I found a really good article on this here.
