As we unpack all our moving boxes and start setting up the household, it seems like a good time to reflect on the Laws of Household Physics.  These are the unspoken rules just about every family is governed by.  These laws are every bit as real as every other law in the universe.





  • A child’s eagerness to assist in any project varies in inverse proportion to the ability to actually do the work involved.
  • Leftovers always expand to fill all available containers plus one.
  • The availability of a ballpoint pen is inversely proportional to how badly it is needed.
  • The same clutter that will fill a one-car garage will fill a two-car garage.
  • Three children plus two cookies equals a fight.
  • The potential for disaster is in direct proportion to the number of TV remote controls divided by the number of viewers.
  • The number of doors left open varies inversely with the outdoor temperature.
  • The capacity of any hot water heater is equal to one and one-half sibling showers.
  • Place two children in a room full of toys and they will both want to play with the same toy.


Do you have some Laws of Household Physics, that I didn't mention here, which seem to be present in your home?
