Henry Ruschmann accidentally invented glitter when he was trying to figure out a way to put discarded plastic to use. 01:55.
In its present form, glitter has only been around for about 75 years or so. However, scientists have found cave paintings over 2,000 years old that include mica flakes that give the paintings a sparkly appearance. Modern glitter as we know it was invented in 1934 by a New Jersey cattle rancher named Henry Ruschmann. Henry also dabbled as a machinist. His hobby led to the accidental discovery of a process that used a machine to precisely cut plastic films into thousands of tiny pieces.
