The most recent incident took place Saturday during the Rocky Mountain Lacrosse Jamboree at a park in Littleton, Colorado. Witnesses say the bounce house was blown about 300 feet across the park before it finally came to a stop.
"All of a sudden, it picks up, and there's a girl going down the slide. She flies about eight feet in the air," Vanessa Atencio told KUSA. The girl was ejected instantly, according to Atencio, though the house continued to roll across the park.
"As the wind picked up, it would tumble," another witness said. "Like a bag in the wind."
A 10-year-old boy was trapped inside as the house blew across the lacrosse fields.
The girl was treated for minor injuries at the scene; the boy was taken to a local hospital for an evaluation, but avoided any serious injuries.
