Simply put the juice bag in the freezer. Put the cola in the fridge. As soon as the juice is frozen, take it out and mix it with the hand blender.
Pour into a glass and add cola to taste. Then serve with a straw. Warning: Do not drink too quickly, otherwise you will get a headache.
Tip: Before freezing, the juice can also be poured into a crushed ice ice cream bag, then it goes even faster. Other variations are of course also possible!
