How does colour changing bubble bath work?
The bubble bath has a dye added to it called Bromocresol Green which is a pH indicator, it will change colour as you change the pH of the bathwater - how acid or alkali the solution is. (Interestingly the one colour it never goes is green!)So as you dilute the bubble bath, which starts off slightly acid, the pH then gets higher and the water becomes more alkaline, making the Bromocresol Green change from orange to blue. If the water becomes acid again it will change from blue back to orange.
