Mock light saber duel critically injures two clue-impaired fans

"Two Star Wars fans are in a critical condition in hospital after apparently trying to make light sabres by filling fluorescent light tubes with petrol [gasoline]. A man, aged 20, and a girl of 17 are believed to have been filming a mock duel when they poured fuel into two glass tubes and lit it." Link (Thanks, Nick)

Reader comment: John Horner says,

Despite the fact that it's the BBC saying so, I find it hard to believe that anyone poured gasoline into a fluouro tube then *lit* the damn thing, not expecting to get hurt. This story from british tabloid the Mirror says the things accidentally exploded. They're still astonishingly short of a clue but perhaps not as insane as made out by the BBC story. Short answer, nobody knows exactly what happened.
