When I was a kid, I learned that potassium reacts extremely violently with water. During Biology class, my teacher related a personal anecdote about a student who had accidentally tipped over a tiny, open container of it into one of the science sinks (which happened to have water in it), and the resulting explosion made a 4ft wide hole in the 12ft high ceiling.
As a kid, I thought that was ‘way too cool.’
And then I got to thinking. Bananas are high in potassium. Very high in it, in fact. And our bodies are 95% water.
I wondered why bananas didn’t explode when we ate them.
Now that you’ve thought about it, don’t you wonder that too?
(Actually, I guess it’s because the potassium in a banana is bonded to a bunch of different elements, thus nulling the ‘explosive’ factor. Freaky, huh?)
