With the help of her son Carson, Holly lined up seven different brands of bottled water on the kitchen counter, plus a glass of water straight from her kitchen tap. Using pH paper test strips (which can be found at your local drugstore or Walmart), the mother-son duo conducted a fascinating science experiment to test the pH of all of the bottles and see if they’re either alkaline or acidic. “As we know, acidity causes cancer,” Holly says.
