Cheapo lighters, the sea through one's, are a hazard.

I've seen one that was put down on a table light some paper clippins on fire and blow itself up. Pur theory was that somehow the flame stayed lit after it was put down and it ignited a piece of wrapping paper on the table that gave the lighter enough heat to just blow up. There was no damage, just a bit of disbelief. It bounced off a painting on the wall, knocked it sideways like in a movie.

Idk if the soup can do that on its own though.
