A cheap weighing device that resembles a land mine with
a 0-300 pounds dial in the top. People place them in
their bathrooms so that checking their current wieght
periodically is easier. People never choose to believe
the results of the scale's measurement. People
only believe what they want to believe. So they tend
to consider the bathroom scale inaccurate ("It's weighing 20 pounds heavy."), and continue their bad habits.
