Maria celebrates her 18th birthday today. Ten of her friends were invited,only one of them( Mr. John)has diabetes,and she knows that,thats why she bought 9 normal coca-cola cans and one coca-cola zero can for him.

She poured each can in a big Coke glass.As she went to bring something from the other room,somebody put the glasses on a serving plate randomely.

Why did you do that? she said angerly..

I wanted to help you...sorry...whats wrong with that?

How can I give Mr. John his Coke now?

all the glasses are very similar,and containing the same amount of Coke.

all the Cokes tastes the same.

can you help Maria to find the glass with coca-cola zero?

Note: they were at her appartement(No lab. procedures).

Agreed that they taste the same, but they have slightly different shade of colour. Look hard and find out.

use one of the diabetic blood sugar test strips to find the sugar free glass?

Pretty sure Dej Mar guessed this way back in post #5:

Though aspertine can play a part in the reaction, the reaction of a Mentos with normal Coca-cola and Coca-cola Zero would be about the same. Thus, the Mentos test fails.

What Maria can do is ask Mr. John for some glucose test strips (as a diabetic, he most likely carries a few with him). A drop of cola applied to the test strip will indicate whether sugar is present in the soft drink.
