Mac N Cheese Paradox

Make one box of mac-n-cheese, kids scarf it and clamor for more.

Make two boxes of mac-n-cheese, kids eat some, but there’s more than a single box left over.

I don’t entirely understand this. I suspect this is a real-life instance of the Banach-Tarski Paradox, but I’m not sure.

One of the consequences of this paradox is that when I have made two boxes, and told the kids it was one box, then they ate all of it.
