The 1920's was full of inventions and big improvements. I will be talking about a few I found interesting.
The first interesting invention I found is 3-D movies. Amazing enough, the year was 1922 when the first 3-D movie came out. The movie was called The Power of Love and was shown in Los Angeles. Spectators wore glasses with one red and one green lens. Although 3-D movies are not huge today I think this was important because it lead to improvements in regular movies.
I also found that the hair dryer was invented in the roaring 20's. While the hair dryer its self was not invented in the 1920's, the idea of having a portable one to use at home was. The first at home hair dryer that came out in the 1920's was large and heavy and over heated a lot. The main focus in the 1920's was to make it lighter and change the material the dryers were made of. I am very appreciative of this improvement since I use a hair dryer almost everyday.
Another invention of the 20's is the Q-tip. Theses were invented by Leo Gerstenzang. He put cotton on both ends of toothpicks and called these "baby gays." He eventually changed the name to "Q-tips" with "q" standing for "quality," and this became the most famous name for cotton swabs.
The automobile was another big improvement in the 1920's. Cars in the 20's often had break downs and were not able to have a low clearance like cars do these days. A big deal in the late 1920's was the release of the "new ford" or the Model A, which replaced the long-standing Model T after 18 years of production. Cars also improved in the area of customer satisfaction. They became available in more colors, and had perks like heating, and became easier to drive and maintain.
Interestingly, the roaring 20's came with the invention of the Lie Detector.The lie detector was invented in 1921 by John Augustus Larson. Larson was a police officer in Berkeley. His model is officially called the polygraph and was based on a persons blood pressure, pulse, respiration, and skin conductivity. It was used in forensic investigation. Personally I think this is the most interesting invention of the 1920's.
