A highlighter is a felt-tip pen filled with transparent ink. Felt-tip pens were first invented in 1952 by Sidney Rosenthal, who attached a wool tip to a glass ink bottle. In 1962, Yukio Horie of Japan took the idea further by creating a fiber-tip pen (using bamboo fibers) that used dye instead of ink. In 1963, the Avery Dennison company introduced their "Hi-Liter," which was a fiber-tipped pen with translucent ink. While initially the Hi-Liter was available in pastel colors, the company introduced a flourescent yellow in 1978, still the most popular highlighter color today.

I used to color my nails with highlighters before my mom let me use fun colored nail polish. Anyone else?
