Kepler Ball

HOW CAN RHOMBO BLOCKS FORM A BALL?

 RHOMBO blocks hold together magically
   Each face magnetically attracts every
       other face in not one but two ways.

Each set of RHOMBO blocks comes
   assembled in the mysterious form of a ball!
     The full name for this ball is a rhombic
         triacontahedron,
             which means that it has 30 faces.

 We have named it the Kepler Ball after the great
   astronomer Johann Kepler (1571-1630), who
     described it in his book “Harmony of the World”.

   Can you recreate the Kepler Ball?
       It is easier than you think!

   Hint: There are two known
       methods to build the Kepler Ball.
         Can you discover a new way?
