Jet Ski<br>My first time on a jet ski was fun. My uncle was on the back. I was getting too close to a rock wall. He yelled at me to stop. We both fell off.
The uncle fell in water
Water is the only thing people logically jet ski on. Water is not mentioned but it is obvious that when they both fell off the uncle fell into water. It was difficult because water was not mentioned.
