Water's ior is 1.3333, or 4/3. 1.5 (for Ball_1) is OK for glass. Diamond's ior 
is about 2.5 and is the largest for natural substances. The ior of 3.5 for 
Ball_2 is prety extreem and un-natural!
Add some dispersion, it helps add realism.
If you want photons caustics, you need to add a photons block in the 
global_settings.
