PolyBall

The Problem:

You probably know how many coins can be placed on a flat surface so that they all touch an identical coin in the middle…

Can you explain why this is the maximum ?

 Now can you imagine how many tennis or golf balls can be arranged, in 3-D space, so that they all touch an identical ball in the middle ?

Is there more than one way to do it ?
