A magician was boasting one day at how long he could hold his breath under water. His record was six minutes. A kid that was listening said, "thats nothing, i can stay under water for 10 minutes using no types of equipment or air pockets!" The magician told the kid if he could do that, he'd give him $10,000. The kid did it and won the money. Can you figure out how?
The kid didn't say he could "hold his breath" for that long, I notice, so how about strolling through the Mersey Tunnel, say? He'd be "under water" for some time, but using "no types of equipment or air pockets" there.
