National Geographic Channel institucional campaign based on the tagline "Did you know..." where several NGC curiosities are unveiled. The big prize was a expedition to Patagonia. Using public scales existing in the streets of Lisbon, passers-by were invited to weight themselves. Their weight was printed in NGC cards with the analogy to the NGC curiosity: "Did you know that your weight on the moon is six times lower than on the Earth?"
