Iced tea has existed since the early 1800s, but it became a national sensation at the 1904 St. Louis World’s Fair. Richard Blechynden, a tea merchant, was trying to promote hot tea from India, but the weather was so oppressively hot that fairgoers were uninterested in hot beverages. In a moment of desperation, he poured his hot tea over ice cubes. The resulting cold drink was an instant hit. This event changed American tea culture forever; today, approximately $80\%$ of the tea consumed in the United States is served on ice. This shift also popularized the 'iced tea spoon,' a long-handled spoon designed to reach the bottom of tall glasses to stir in sugar.
