Much like the work that 7-Eleven Slurpee machines do, a rotating machine that keeps ice constantly moving is key to creating the perfect slushie. Thai street food vendors also dump water and ice into the vat. In response to a YouTube video, one commenter asked why the water being poured in was slightly brown, prompting the account owner to explain that it was due to the addition of salt.
After adding salt to the ice water surrounding the Coke bottles, a chemical reaction occurs, preventing the ice from melting as rapidly as it would if they were sitting in plain water. Saltwater can reach colder temperatures than plain water, so soda bottles also freeze much faster. Salt, ice, and constant motion are the only factors needed to make these simple Coca-Cola slushies from Thailand a reality.
Of course, if you can’t make it to an Asian street food stall anytime soon, you can concoct icy beverages at home. What’s even better about making a homemade version of this sweet refreshment is the potential to add a boozy twist to the mix, like in our easy wine slushie recipe. You don’t need to buy a bulky slushie machine to make it: Use your trusty blender to make the magic happen. We hope Thailand’s Coke bottle slushie concept gets you thinking about other creative summer slushie ideas.
