I am 12 years old! I would like to recommend a very simple Korean cold drink that I often make at home, without any fumes or dangers. The method is: Dig the watermelon into balls or cut into pieces, put it in a small bowl, then pour pure milk to cover the watermelon, add a little Sprite and it will be ok.

I fell in love with drinking pure milk because of this cold drink.

Hope this helps you! ! !
