I am amazed at just HOW popular certain products are. For instance, Cheerios is the most popular cereal with over 100 million boxes sold per year. That's 4 per second.
Campbell's Soup has been selling soup for over 100 years. They sell 6 Chicken Noodle Soups per second.
Now the I Phone - amazing, considering the cost - 7 iPhones sold/sec
But this may be the most remarkable to me: yes I know the world loves a pizza. But just Domino's Pizza alone sells 34 pizzas per second.
