Passengers on the Titanic could withstanding freezing air temperature
for several hours on the deck of the doomed liner.
Once in the freezing water, they survived for no more than 15
minutes or so.

One popular method of water purification puts distilled water
through a packed resin column to provide deionized water, which
is verified by attempting to pass an electric current though it
and noting its high resistivity.
