The video goes through the process of making a solution from red cabbage. The video begins with a quarter of red cabbage being chopped. The cabbage is then placed in a blender and 250 ml of water is added before blending it all together. The liquid is then strained through a sieve into a measuring jug. The liquid is then poured equally into four sample glasses. Each glass is labelled differently, one being bicarbonate of soda, a teaspoon of bicarbonate of soda is then added to the relevant glass.
