On the streets of New York City a balloon salesman knew how to attract a crowd. Before making his first sale, he took a white balloon, filled it with helium gas and it floated into the air on the string. Next, he inflated a red balloon and then a yellow one. As children gathered around to buy his wares, a little black boy looked up at the balloons and eventually asked, “Mister, if you filled a black balloon, would it go up, too?” The man bent down and looked the boy in the eyes and said, “Of course. It’s not the color of the balloon, it’s what’s inside that makes it rise.”
