I learned some things yesterday:
1. If you put dish soap in a dishwasher, it foams right up.
2. Dishwashers have a vent at the bottom that allows this foam to exit the dishwasher.
3. If you put a lot of dish soap in (say, filling both soap trays) a lot of suds will form (say, filling the room with bubbles).
4. If you do these things in the break room at work, you will never, ever, ever hear the end of it.
Ignore these things at your own peril.
