Why does a bar of soap produce a great lather when it’s new, then not at all when it’s smaller?

It’s supposedly the same soap through and through, all the way to the core of the bar, right? Why does it react so differently to water and being rubbed on skin when it is reduced to a sliver?

It might have something to do with the filler used in soaps being lighter than soap molecules,causing it to rise to the top as the soap sets and hardens. I have always found that as soap bar is used more and more, its cleaning ability increases and foaming ability decreases.
