Ask anyone about the color of bubble gum and they’ll invariably say “pink.” In 1928, Walter Diemer accidentally created the first successful batch of bubble gum while playing around with different recipes. He made it pink because, at the time, that was the only food coloring available in the factory. When contemplating whether to discard or memorialize something, it might be wise to chew a piece of bubble gum and think about the initial reasoning behind that particular tradition.
