Hilariously I went on this tangent last night, and you can do this with a cooler, to give you "directional freezing" which I also heard people call "lake effect freezing". I'm trying it out this weekend for fun:

Wow, thanks for that! I actually have a few of those exact same spherical ice molds. If I can find a cooler small enough to fit in my euro-freezer I'll have to give this a try.
