Potassium is used a lot as an electrolyte, both in industrial applications but especially in biological processes. While your body can substitute other elements on hand for electrolytic reactions if it runs out of potassium, it's not going to feel very nice and can eventually lead to some lethal conditions.

Bananas are not actually the most potassium rich foods out there. Apricots have a lot more, and there's quite a lot of it in beans, potatoes, and dark leafy lettuce.

Potassium can also form an amalgam with sodium called "NaK" which resembles Mercury in that it is a silvery liquid at room temperature but is much lighter. It also instantly bursts into flames when exposed to air.

Potassium is mildly radioactive.

See

"Banana equivalent dose."

Wow, I am surprising myself with how many of these I can remember despite never studying them in school. Screw you, high school chemistry! (which I never took)

Also Bananas and Potassium have the most naturally occuring radioactive isotopes, making Bananas the most naturally radioactive foods because of the high chance of radioactive isotopes of Potassium. Eating 600 Bananas is the equivalent of getting a Cat Scan.

Sodium free salt?
Try KCl, Potassium Chloride!
It works just fine as NaCl.

of course it is molestia with the banana, why am i not surprised. actually i am kinda happy it is her <3

bad joke

she can ride my bananas X3

Virtually everyone who's paid the least bit of attention in chemistry class knows about the violent single-replacement reaction that occurs when you expose metallic Sodium to water.
Metallic Potassium has near identical properties, except the reaction yielded is much more potent.
