"No prob!" Frisk gets out their slate again, and the cooler disappears. Seriously, somebody should've thought to check those things for utility in smuggling, because if Frisk had just slightly looser morals they'd be turning a massive profit right now. "Coffee, coffee... there should be a coffee maker somewhere in the lounge. C'mon, follow me." Frisk gestures for Vimes to come with them as they walk away.

Their jaw unhinges when Vimes explains his unfamiliarity with the concept of gravity. "Okay. Um. How do I explain this." They sigh, pinching the bridge of their nose. "Every object in the universe exerts a force that pulls other objects towards it. The larger the object, the more powerful the force. Since this force pulls stuff in in all directions, matter tends to accrete in a sphere. Which creates planets. And since, like I said, gravity pulls stuff in from all directions... you can live on the bottom of a planet and not fall off."
