Universal indicator is a mixture of several indicators displaying a variety of colors over a wide pH range so it can be used to determine an approximate pH of the solution.

  • That was quite enjoyable. I especially like the music track.

  • More simple than that... read the explanation in the "more info" section.

    Throughout the whole experiment, the same acid is added.

  • @yongrenjie I don't suppose it'd do anything if he constantly drank universal indicator?

  • @amocrass2 you bring the indicator, i will do handjob over that. if there is no way to mix them inside :D

  • @Heart111ful well if you MUST know, semen is slightly alkaline (it has to neutralise the acidity in the female reproductive tract), so it'd probably turn up a slightly dark green.
