Acids
Item Tested: Neutrogena Cleanser
Prediction/Comments: It was a bit obvious that this cleanser would be acidic, with its blunt front label and with how often I have to deal with its sour taste. The result was no surprise.
Conclusion: The blueberry juice+cleanser solution has soap bubbles and a deep red/pink colour to indicate its acidity. It is an acid.

Acids
Item Tested: Soap
Predictions/Comments: We've all been blessed with the bitter taste of soap at least once in our lifetime, so we guessed it would be a base.
Safety: Avoid having this substance enter the eye or being swallowed. It may sting, irritate or swell the eye or irritate and dry the throat. If such situation occurs, rinse eye with water or drink lots of water.
Conclusion: The resulting colour was a red-purple colour, so this soap is acidic. We were confused so we did some product research and found that this soap contains citric acid.

Acids
Product Tested: Nestea
Predictions/Comments: We all know well that Nestea is tea mixed with lemonade, so it was likely that it'd be acidic because lemonade, or lemons in general, contain citric acid.
Conclusion: The result was an red-orange colour which indicates that Nestea is acidic.

Acids
Product Tested: Elmer's School Glue
Prediction/Comments: I, Kerra, specifically thought school glue would be neither acidic or basic, considering an unfortunate accident that occurred years ago when the class had determined that school glue tastes like french fries. But, between choosing one of the two, I thought glue would be acidic because glue can taste sour.
Conclusion: Acidic. The colour looks really blurred put the approximate pH is around 1.

Acids
Item Tested: Apple Juice
Predictions/Comments: We were a bit unsure whether apple juice was a base or an acid, but then we thought....sour apples..yes...bitter apples..? No, not yet. And so, we thought it would be acidic.
Conclusions: YES! Apple juice is acidic, as we'd guessed, with a likely pH of 2 or 3.

Acids
Item Tested: Orange Slice
Predictions: The word citrus does come to mind when looking at an orange, and can be followed by the word citric acid, which can help us be pretty sure that oranges might be acidic, not to mention its powerful sour taste.
Conclusion: An orange slice, to nobody's surprise (hopefully), is acidic, with a probable pH of 2.
See the video below for a better idea of what we did.
Acids
Product Tested: Vinegar
Predictions/Comments: Acid is a must for vinegar, considering the word 'acetic acid' (also known as CH₃COOH) is labeled right on the container. And, of course, with its notorious sour reputation in the kitchen world, it should be acidic.
Conclusion: Vinegar is, indeed, acidic, with an approximate pH of 4, when referring to the pH colour indicator in our reference slideshow.

Acids
Product Tested: Lime
Predictions/Observations: The familiar sour taste of limes was a definite promise of an acid. As the juice of the lime was squeezed into the blueberry juice (our pH indicator), the indicator turned into a more vibrant and bolder red- confirming its acidic status.
Conclusion: Limes are acidic, with an estimated pH of 2 or 3.

Acids
Limes, like oranges, contain citric acid, so the pink colour of the blueberry juice confirmed it was an acid.
Acids
Apples, contain citric acid, so it was likely that the blueberry juice would turn into a brighter and lighter red. In fact, it turned into a transparent pink.
Acids
I put orange juice to the test using my blueberry juice indicator. Orange juice contains citric acid, like most fruits. Although the acid is a weak acid, it can still irritate the eyes if they come in contact with it.
Here were the acidity results.

The blueberry juice had turned into brighter and lighter shade of red, which confirmed that the orange juice was acidic.
