You are walking near a large lake with your standard poodle playing fetch in standard atmospheric conditions. You accidentally overthrow the ball, and it falls in the lake and starts sinking! When the ball lands at the bottom of the river, you know for some reason that the pressure is 6 atm. You also remember from a scuba certification class that the maximum safe distance you can dive without scuba equipment is 60 feet. Your friend has scuba equipment on hand but is a 5-minute drive away
