Whats happening? By adding sugar to the water, it dissolves and become invisible. Suddenly this changes the weight of the water. The more sugar is added to the water, the more the weight of the water increases. In other words, the water becomes denser (for the same amount of liquid it is heavier). In our experiment, the water with the greatest density is the red-coloured one, and the one wit he least density is the purple-coloured one. That's why it floats on the other liquids.
