Trivia: Kleenex was invented to serve what purpose during World War I?
A bandage
A gas mask filter
A gun cleaner
An extra sock layer
Correct Answer: A gas mask filter
So why is this answer correct? : You know it as the brand-name of facial tissue, but during WWI folks carried handkerchiefs instead of tissues. Kleenex was originally invented for use as a gas mask filter. After the war, Kimberly-Clark remarketed Kleenex in 1924 as a makeup remover.
