„Hi! Have you already found out the riddle's solution?“
„No, not yet. But I'm thinking about what would happen if the captain threw a wodden beam of 50 kg* overboard instead of the gold. If we consider only the ship at first ...“
„ ... the ship looses 50 kg of its weight if the wooden beam is thrown off the ship. This means that it isn't not pushed as deep as before into the water and therefore displaces less water. It displaces exactly 50kg of water less than before.“
