The current flag was designed by a 17-year-old

Our current 50-star flag was designed as part of a high school project by 17-year old Robert Heff. It was 1958, and there were only 48 states at the time but Heft had a hunch Hawaii and Alaska would soon be granted statehood.

His teacher gave him a B- but went on to update the grade to an A after Heft submitted his design to the White House, eventually leading to a call from President Eisenhower that it had been selected as the official U.S. flag. This is one of the 20 American flag facts that will amaze you.
