Today’s science question is brought to you by… my freezer.
So we have ice cube trays, which we fill with water (duh) and drop in the freezer. Every now and then, when I take the tray out, I find one or two ice cubes that have a mysterious spike sticking up into the air. Note that nothing is above the trays, so it’s not like there’s dripping water to make this “inverse icicle”.
The question: how and why does this happen? Why only occasionally?
I expect some research and answers from the handful of science geeks who I know read this. (Yes, Tad, this means you.)
