one more question! Does the combination of water and cylinder shaped glass creats the effect of cylindrical lens?

Thanks ranger :)

! Many thanks for your fast reply :) Would you mind adding a more detailed explanation or to direct me to website that will explain it more clearer?

i need an explanation for this situation. i've inserted an pingpong ball into a glass full with water (the glass is made out of thick glass if it matters somehow?). Now what happened is that the half of the ball that is in the water looks much bigger than the half that is not in the water...
