Saturday afternoon, Skyhigh Flyboards in Minneapolis posted a video to Facebook.
It shows a boat on a lake, and a bunch of smoke is coming from it.
Then a person erupts from the water, soars over the boat with a flyboard – it's like a water jet pack for your feet – and starts spraying water on the boat.
KARE 11 says the incident happened on Cross Lake, just north of Brainerd.
The owner of Skyhigh tells the station that his family saw the fire and went to the rescue. It was a matter of minutes before the fire was extinguished.
