What is how to make clear ice?

Making clear ice is a fun project that yields impressive results. The key to clear ice lies in directional freezing. Regular ice freezes from the outside in, trapping impurities and air bubbles in the center, which causes cloudiness. Directional freezing forces the water to freeze from one direction, pushing those impurities to the bottom. Here's how to do it:

1. Choosing Your Container: An insulated cooler is a good option. The insulation ensures that the water freezes directionally from the top down.
2. The Freezing Process: Fill the cooler with water, leaving some space at the top. Place the cooler in your freezer without the lid.
3. Freeze Time: The freezing time depends on your freezer and the size of the container. Typically, it takes between 24-48 hours. You want the ice to be mostly frozen with a small amount of unfrozen water at the bottom.
4. Removing the Ice: Take the cooler out of the freezer and invert it. The clear ice block should slide out easily.
5. Discarding the Impurities: Pour the unfrozen water (containing the impurities) out.
6. Cutting the Ice: Use a serrated knife and a hammer (or an ice pick) to score the ice and then gently tap along the score line to create your desired ice shapes. Be careful!
7. Water Quality: Although directional freezing removes most impurities, starting with filtered or distilled water can further improve the clarity.
