    Science is the answer. Light gets refracted though the water. AKA light bends.

      Great job! You stayed awake in science class and you got this one correct. :D

    I think the glass is reflecting the stripes on the table rather than showing the ones behind it.

      That’s an interesting post and it could be the answer.

    Why? Nothing more than basic optics. The water diffracts the light coming through it and it appears sinusoidal because the glass is tapered and giving a varying path length.

      Very good! :)

    This is standard optics, and the light from the background image is being REFRACTED (not diffracted) by the distorting lens of the glass. What IS interesting is that the image in the centre is ROTATED, not parallel with the background, showing that it is possible to make lenses that rotate an image.

      Great job. :)
