this happened many years ago - before the days of instant oatmeal .
mrs h always boiled up a pot of hot oatmeal for me the night before , just reheating it in the morning .
i noticed that ROLLED WHEAT was cheaper than the oatmeal and brought some home .
mrs h told me that the wheat was not right as a replacement for the oatmeal - it was quite coarse even after boiling it for a long time .
i knew better
i put the wheat flakes in a pressure cooker , added water and started it up .
i went into the living room to read the paper ... and BOOM it went !
rushed into the kitchen - the pressure gauge had blown off and hit the ceiling putting a dent in it - the wheat had shot up through the "blowhole" and covered the ceiling !
what a mess ! we tried to scrape off the wheat-glue as well as we could but when we moved out three years later there was still some residue left on the ceiling - the next tenant should have paid us for it
i was VERY QUIET and refrained from further kitchen experiments :wink:
ps. ehbeth does not seem to have suffered much from the explosion
