Learn how to use silicone ice cube trays to make perfectly sized ice for your bkr bottle, keep water cold longer, and avoid common mistakes.
Quick Answer
Use a silicone ice cube tray like the Everly Ice Tube Tray to freeze water into slim, bottle-friendly cubes that chill your bkr without watering it down too fast.
Why Silicone Ice Trays Work Best
Silicone ice trays are flexible, so you can pop out the cubes easily without cracking them. They are also dishwasher safe, making cleanup simple. The Everly Ice Tube Tray uses the same soft silicone as bkr sleeves, so it is gentle and easy to handle.
The slim tube shape fits through bottle openings, unlike bulky standard cubes that can get stuck. This makes them ideal for narrow-neck bottles.
Steps to Freeze and Use Ice Tubes
- Fill the tray: Fill each tube with filtered water, leaving a tiny gap at the top for expansion. Avoid overfilling, as this can cause the tray to warp or the ice to stick. Use filtered water for clearer ice and better taste.
- Freeze flat: Place the tray on a flat surface in the freezer. Make sure it is level so the water freezes evenly and the tubes come out uniform. Avoid stacking items on top while freezing. Check that the tray is level before closing the freezer door.
- Pop out the ice tubes: Gently twist or flex the tray to release the ice tubes. If they stick, run the bottom under warm water for a few seconds—do not use metal tools that could scratch the silicone. Twist, don’t pull, to prevent breaking the ice.
- Add to your bottle: Drop 2-3 ice tubes into your bkr bottle. They are slim enough to slide through the opening easily. Fill with cold water and enjoy. Start with fewer cubes and add more if you prefer extra chill.
