Having ice cubes is a great luxury. Sure, they are just water, but they are a luxury because they can be difficult to make. I know what you’re thinking. Ice cubes? Hard to make? Stay with me. Imagine opening your freezer. Now imagine opening your freezer with a fresh ice cube tray. You have to be so careful not to spill it that you often don’t even want to bother going inside the freezer before the ice cubes get made.
This spill-proof ice cube tray is basically the tank of ice cube trays. Nothing is going to stop this thing from freezing your water without a single spill. I’m not saying that you’d need ice cubes in a post apocalyptic wasteland, but if you did, you’d want this ice cube tray.
