    1. We had the most amazing conversation at the diner table today, induced by a question by our son: “How heavy is air?” As it turns out, 1 m³ of air weighs about 1.3 kg! And the weight exerted on the human body by the atmosphere is about 10 tons! 🤯

    Next question by the kids was, of course, whether we could, if there were no air around us, fly around just with the propulsive force of our farts. 😁💨
