The Science:
The science behind this experiment involves the PH scale. Oranges are acidic fruits, making them lower on the PH scale. The baking soda is basic, so it is on the opposite side of the scale. When the two opposites mix in your mouth, a reaction occurs resulting in the creation of carbon dioxide bubbles. This is why you feel fizzing when you bite into the orange sprinkled in baking soda.
