I believe that it was 1989, or 1990, when two researchers, working on ideas similar to Pons and Fleischman's work, had made a tightly sealed vessel of about 1 liter capacity to contain their experiment. The experiment was only about 20 seconds old when the vessel ruptured catastrophically, killing both men and badly damaging the columns.
Nobody has ever fessed-up about what was in the vessel, but witnesses said that it was quite benign for the 24 hours that it had rested on the bench before being closed. It was fully self contained, and was not heated, or even connected to anything else.
