with apologies to Ogden Nash...
And the great thing about the potato test is that you can eat it afterwards!
Not after you soak it in phenolphthalein!
I challenge you to go to your local pharmacist and ask him for some 'phenolphthalein'. Tell him you need it for polarity testing. See what he says.http://www.thefreedictionary.com/phenolphthalein
Further to previous -- that comment was meant entirely in fun. My warped sense of humour is occasionally, regretfully mistaken for denigration.
It's an acid-base indicator! It's a laxative! It's two, two, two things in one! So, not only can it help you tell positive from negative, it can let you know if you're coming or going!
