This week the inventor of the ubiquitous red Solo cup died, at the age of 84.

According to People Magazine, "Hulseman started working at Solo Cup Company when he was just 18. The company’s cone-shaped paper cups debuted in the 1940s, and continued providing all manner of disposable tableware through the 1950s and ’60s, until the 1970s, when Hulseman was credited with inventing the project that changed drinking culture forever."

The red Solo cup has been the subject of songs, and the main component of many beer pong matches. You probably have some in your house right now!

Did you know the lines inside the red Solo cup denote different measurements? The lines inside give one ounce measurements for liquor, five ounce measurements for wine, and 12 ounces for beer (or soda).
