How many balls?

[4073709 2]

See if you can work out how many glass balls are in the image below:

A few clues. Some of the balls are only visible as a reflection. Dont count reflections. Dont count balls inside other balls. Its between 3 and 10.
If anyone posts an answer I will show the scene file.

It's a CG image, ergo there are NO balls.

There are 6 balls:

I am actually working on a box with reflective sides / top / bottom to build an environment where I can recreate some of this type of image as a "REAL" photograph.
