Puzzle: A glass of water sits on table in a room at 56° Fahrenheit. The glass is a 1 pint/20 fl oz measure that is full to the brim with water, floating in that water is some ice. Protruding from the surface of the water in the glass is a mass of ice equivalent to 1 fl oz, that is 1/20 of a pint.
When the ice has melted, how much water will have overflowed the glass on to the table?
Please excuse the rather rushed illustration, I knocked it up quickly.
The first person to answer this puzzle got it right, at last my faith in humanity has been restored, what a relief.
