Marisa asked the Naked Scientists:
I have ice cubes in my freezer at our office that form long, skinny spikes when freezing. Normally, 1 or 2 in the tray of 14 form 1 and 1/2 inch tall spikes. We have three ice cube trays in our freezer and only the tray on the far right forms these ice spikes.
What causes this?
What do you think?
