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!

Notes
*Please note that in the video I stated that you should preheat your freezer to negative 32F. While this will work perfectly fine, I meant to say 32F and this is a more standard temperature for preparing ice.
How to Store
Keep leftover ice in freezer for up to 7 years or longer.
