    Is there any local big box store that a person can some. I ran out and hate to place an order for just that. All I can find start at 6 and go up to 8.

    Red Cabbage Juice
    One interesting method of testing the pH of a liquid uses red cabbage juice as a pH indicator. When the cabbage juice is mixed with different liquids, the solution changes color thanks to a pigment in red cabbage called flavin – an anthocyanin. If the color changes to pink, the pH is 1 to 2. If the color becomes dark red, the pH is 3 to 4. If the color changes to violet, the pH is 5 to 7. If the color changes to blue, the pH is 8. If the color turns blue-green, the pH is 9 to10. If the color becomes green-yellow, the pH is 11 to 12. This means that pink and dark red solutions are acidic, violet solutions are either acidic or neutral, and blue, blue-green and green-yellow solutions are alkaline.

    I remembered doing that experiment in chemistry class years ago. Found that tidbit on the internet.
