In the Korean comments

One comment turns the video into a recipe, reading in translation: “Prepare a cup of ice, add Chamisul and Mountain Dew, and watch the 1:4 ratio.” Another points out a moment to watch for: “The hamster keeps trying to clink glasses.”

What the words mean

짠 (jjan, “cheers”) literally imitates the sound of glasses clinking. Here it casually and playfully means making a toast or trying to clink glasses with someone.
