The Scotch Tape of the 1930s

There are tons of new inventions showing up every day, but what about those inventions from years ago that got us to where we are today? In this episode of Unprofessional Engineering, we looked back at the most important and interesting inventions that came from the 1930s. Some HUGE inventions such as nuclear fission and the jet engine are still changing the world and being improved today, where others like the chocolate chip cookie and Twinkies seem like (very important) inventions from the 1930s that can't possibly be improved!
