Eta, the analogy that my son always used for me was of raisin bread dough. The bread rises and expands in three dimensions but the raisin that are spread throughout the dough do not expand, they just get further apart in space and the dough section they are in expands away from the dough section the next raisin is in.
I am not very good at explaining myself here, but it did help me to understand better than the balloon analogy.
What do you, as a professional, think of it?
