Watch From the Inside of a Dishwasher As It Runs Through A Cycle
If you continue to wonder what it looks like inside of a dishwasher as it runs (perhaps in the same way you wondered if the refrigerator light stayed on with the door closed), wonder no more: someone finally put a GoPro camera inside their dishwasher.
BUT: that dishwasher is not full. Maybe it made it easier to see what was going on inside, but it's still wasteful.
