Forget boiling smelly cabbages to extract pH indicator. Red Cabbage Jiffy Juice is bottled and ready to use.

Safe and easy, Jiffy Juice is a pre-bottled red cabbage extract that makes colourful solutions when mixed with acids and bases. Acids, like lemon juice, turn it from purple to shades of pink and red, bases, like baking soda turn it from purple to shades of blue and green.

Just mix up the instant powder with water to make the Jiffy Juice indicator and measure the pH of common household substances like vinegar, toothpaste, orange juice, disinfectant and soft drink.

And because its an extract, one jar goes a long way. Just think how many cabbages you'd have to boil to make this much juice!
