Preheat freezer to 32F (0C)
Uncap water bottle (do not skip this step) and evenly distribute water into ice cube tray.
If using a spatula, now is its time to shine. Use spatula to carefully smooth out ice, eliminating the chance of any wrinkles.
Transfer ice cube tray to freezer and allow to chill overnight.
The next morning, check your ice. It should be frozen solid and can be used at once. Enjoy!
