Crumbs fly off of bread all the time.
Sometimes we notice the bigger, obvious explosions.
But in reality, multitudes of tiny ‘explosions’ of bread crumbs are happening all the time that we don’t see, because they are too small for our eyes to notice.
This is not just true for bread, but also, basically, for the entire world around us, and for ourselves.
We’re constantly interacting and exchanging material & energy with the environment, and it is back with us, all the time.
