The original drink, brought to the state of air foam. You will also need:
oxygen-air mixture - 200-300ml (this is oxygen itself) and a foaming composition for oxygen cocktails - 2g
Such an oxygen cocktail is prepared very easily at home, if there are all the necessary devices. In the store you can find a set for making an oxygen cocktail. From one set, you can cook about 30-200 servings, but it depends on which set.
Juices can be chosen according to your taste and mixed in different proportions. I like this one, it's slightly sour, very invigorating.
