Secondly,our ice is round, so it has less surface area than regular ice cubes. Both these factors keep your drink colder for longer without diluting it The ideal freezing temperature for making crystal clear ice is <u>-0.4F (-18C)</u>. Using a warmer freezer setting will take longer to freeze, while using a colder freezer setting may cause needle-like bubbles to form. Let your tray rest <u>for 3-5 minutes</u> after pulling it out of the freezer. This helps make the ice easy to remove. Prepping for a Party? Make your spheres of crystal clear ice <u>ahead of time</u> and store them in our newly designed accessory, the Polar Ice Tube.
