Crystal clear ice is odorless and flavorless, yet adds a cold crispness to your favorite beverage <span class="a-text-bold">EASY TO USE</span>: 1. Add water 2. Put in the freezer 3. Wait 8-12 hours 4. Enjoy! <span class="a-text-bold">MELTS SLOWLY</span>: Crystal clear ice melts more slowly than regular ice because it is just water (no air bubbles). 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.
