We've heard reports of exploding e-cigarettes before, but surveillance video from a gas station in Owensboro caught the event on camera.
The incident happened this weekend at the Shell gas station on New Hartford Road.
You can see a man, Josh Hamilton, standing at the counter, when all of a sudden his pants burst into flames, sparks shooting across the store.
Hamilton then runs outside and takes off his pants. Bystanders tried to help, when someone finally uses a fire extinguisher.
Hamiltion posted on his Facebook he suffered third degree burns. He tells Eyewitness News it was a spare battery that burst into flames.
