A magician was boasting about holding his breath underwater for 6 minutes. A kid overheard him and said 'I can beat your record and stay underwater for 10 minutes without using any equipment.'' The magician told the kid if he could do that he'd give him $10,000. The kid did it and won the money. How did he do it?
He filled a glass of water and held it over his head for 10 minutes.
