A California woman was rushed to the hospital after her shorts exploded into flames.

The woman picked up some rocks along a beach south of Los Angeles.

She put them in her pocket and she and her family went home.

Hours later, the rocks apparently caught fire.

Experts say these rocks may contain white phosphorous which can be ignited through friction.

Experts say it could be like setting off a road flare.
