Bulky Ball Model

Principle: Try to use pentagon patterns to construct a bulky ball model ( it looks like a soccer ). Actually, this atomic structure is nicknamed as "bulky ball" which is formed by 60 carbon atoms. To be complicated, you might mix hexagon patterns and pentagon patterns to form a big ball or a tube; the two structures are known as Fullerenes and Nanotube. Check the application of those structures, for example, use them to build useful things.
