She told commenters that unlike ice cubes, her trick lasts longer and doesn’t melt down as fast.
In the TikTok video, Vicky Gilchrist (@vickygilchrist_) started off by saying it’s the best summer hack.
She then took a plastic water bottle and filled it halfway with water from the faucet.
“Half fill the bottle, then freeze on its side,” she wrote.
Gilchrist then tilted the bottle horizontally before placing it in her freezer.
Once removed, half of the bottle contained a large frozen mass instead of multiple ice cubes.
She took it back to the faucet, where she filled the other half of the bottle with water, revealing how it instantly chilled.
Some commenters were excited to share they were already fans of the hack.
One person wrote: “I’ve always done this! I still do it with my own water bottles too. Thought this was the norm.”
Another noted how it helped them save space while traveling.
“We did the same thing when we went on vacation. We don’t need extra ice packs for the cooling bag.”
People also offered additional advice for avoiding common mishaps, like not removing bottle accessories prior to freezing.
“I would add not to leave the straw in when you freeze it. I have accidentally trapped the straw in the frozen water,” said a commenter.
Another added that this hack works just as well for bottles that don’t have large openings.
“For smaller openings, you can do it diagonally and it works the same.”
