Do you attempt to verify things you see on social media before sharing them, or just dismiss things that seem to be unlikely? Sometimes I see things that are meant to be funny but it forces me to think about them and then I have to do research. So here’s the deal with bananas:

Anything that contains potassium-40, as bananas do, produces antimatter as the isotope decays. Carrots, red meat, beer, lima beans – you and I – also produce tiny amounts of positrons. The thing about antimatter though is that it does not exist for very long. Every time a single atom of antimatter is created, it immediately cancels out one of atom of regular matter. So if a bunch of bananas lay on your kitchen counter for a week, the total amount of antimatter they contain is still net zero.
