In high school physics we learned that if you bounced it enough times (billions and billions, thanks Carl) eventually it would go right through, when all the atoms in the ball lined up with all the atoms in the wall so as that they each passed through the space in the other.
I think your high school really messed you up man. There's no space between atoms... the space is within the atoms, between the center and the electrons. They spin so fast that they basically create a force field that links them to the next atom... there's no free space for another atom to pass between them, not to mention that neither tennis balls nor china walls are made of free atoms, but rather long long chains of molecules that would all have to pass thru together. A tennis ball atom going between even two china atoms would be like a slow growing vine trying to cross interstate 405 in LA without getting run over by a car. It would be easier to launch a VehiCROSS into space, that's for sure!
