Half a Basketball??

My friend, OYY requested for a basketball cake for her son's Children's Day celebration in school. As she drives like a Grand Prix driver on the highway, I have doubt that the ball will still be in one piece after being succumb to 20km of bashing. Without her knowing my concern, I casually suggested a half basketball cake. I was glad when she accepted my suggestion. At least I know my cake will still be recognisable when it reaches its destination.........

This is what the cake looks like.......
