Coffee and orange juice concentrations with a twist

This question dates back to a time where I used to watch something called The Curiosity Show... Kinda like Bill Nye the Science Guy's show. I just can't recall the answer to this so I'm hoping that someone could shed some light.


I have two glasses of equal size and volume, with equivalent volumes of orange juice and coffee, one beverage in each glass.


Given that I have a hypothetical non-stick, hydrophobic teaspoon on me, if I was to get my teaspoon and take a level teaspoon of coffee out of the coffee glass and put it in the glass of orange juice, give it a stir, and then get a level teaspoon of this orange juice plus coffee mix and put this teaspoon of liquid in the coffee glass and give it a stir... Do I now:


1. have more orange juice in the coffee glass than coffee in the orange juice glass;
2. have more coffee in the orange juice glass than orange juice in the coffee glass; or
3. have equal amounts of coffee in the orange juice glass and orange juice in the coffee glass?
