An egg of Columbus A riddle that is so obvious… once you know the trick

The tale goes that Columbus attended a dinner where people criticized his 'discovery' of America because 'anyone can see a giant mass of land!' So Columbus challenged the critics to make an egg stand on end. No one was able to do it. Then Colombus lightly tapped the bottom of the egg so that it was cracked. The dent in the shell allowed Colombus to make the egg stand upright with ease.
