In reading the article, they made a serious mistake by pumping gallons of gas into the rod holder. To make sure there was no spark of electricity to start a fire, they were taking the leads off the battery.

This is what happened to these guys--a spark was created taking the wires off the battery and the gas caught on fire. Good intentions, just did not execute the way they wanted.
