1. Fueled Rocket: The fueled rocket was a major step up especially for the Military since it meant the future was going to have gas powered missiles. A fuel rocket only requires a few things to work such as: The Casing, Grain, Nozzle, Seal and the Ignition charge. Many improvements have been made on this rocket over the decades. Now fueled rockets have been replaced in many countries by a more sophisticated rocket technology. I love to shoot fireworks that resemble a rocket launch (on a much smaller scale). I can not imagine what a fueled rocket launch would feel like.
2. Band-aid: A mom's best friend. These are used to cover up an open wound. The Bandaid is sticky on both ends and has a small piece of gauze that is in the center of the Bandaid acts as a compression bandage and can help blood to clot and stop the bleeding. There are now different styles and types of Bandaids and they range in size from quite large to the "spot" Bandaid as they are called. There are many Bandaids that have designs or characters on them. These are popular at the pediatrician's offices. They always have the cool Bandaids for the kids. At any rate, this invention, led to other types of bandages used in hospitals across America.
3. Traffic Lights: Simple. Red, Yellow, Green. Three simple colors. Red means stop, yellow means caution and that the light is about to turn red. Green means go. Before traffic lights were invented, everyone had to be careful not to have a wreck when going through an intersection. I remember intersections that used to be 4-way stops, they have now been converted to traffic lights. This is done of course, for the safety of the motorists. Everyone is in such a hurry these days that 4-way stop areas are just more dangerous than they are worth.
4. Wind Tunnel: The first ever Wind Tunnel was in the 1940s during WWII. The US constructed during 1941 WWII era, one of the largest wind tunnels at that time at Wright Field in Dayton, Ohio. This wind tunnel starts at 45 feet and narrows to 20 feet in diameter. Two 40-foot (12 m) fans were driven by a 40,000 hp electric motor. Large scale aircraft models could be tested at air speeds of 400 mph (640 km/h).
5. Hair Dryer: Used as it's title suggests. It does dry your hair by using electricity. There are settings for the warmth of the dryer air and also, how hard the hair dryer will blow. I don't know about you but, my hair is out of control without a hair dryer so, I can't imagine life without one. I even keep a couple of spares around the house just in case the hair dryer I am currently using decides to suddenly stop working. They seem to just kind of give out with any warning.
6. Lie Detector Test: This invention is also called a Polygraph and was invented in 1921. The machine hooks up to a person and measures the heart beat, pulse and blood pressure to determine if the person is telling the truth or not. Although these machines are not always 100% accurate, and are not admissible in court but, they are still considered 80% accurate and they aid in leading the police in the right direction when prosecuting a case. Very few people are truly good at it and can act calm like they are not guilty. I have never tried a lie detector test or anything like it during my life.
7. Radio (Transmission): Without Radio Transmissions we wouldn't have radio stations to listen to today. Also, due to radio transmissions we are able to have walkie talkies and two way radios. Originally CB's just had one volume level. Now they come with multiple volume levels, a mute button and other fun. The first radio I every got played cassette tapes and the radio. It came with a microphone and was actually called a boom box or a jam box, if I remember correctly.
8 .Packaged Sliced Bread: You always hear the expression that it is better than sliced bread. I love that metaphor. I always joke and say that I was Italian in my former life...he....he....There are so many different kinds of bread from white bread, whole wheat bread, white wheat bread and many others. Some of my favorite stores in the Birmingham area are specialty bread stores. If I want to do something nice for myself then, I will go by and by a special loaf of bread or a certain dessert or cookie.
9. Radar: The development of the radar lead to the invention of many other radar systems. Some that come to mind are Military Radar and Doppler Radar. Radar uses radio waves to determine to the range of objects. Radars are used in the ocean and the sky and space. Most popular or well known is probably the Doppler radar. Living in Alabama where we are stricken by tornadoes, the Doppler radar is a great tool to have on your side.
10. Kinescope: This is recording a television program made by filming the picture from an actual video monitor. This had to be done back during the time when electronics were not as advanced as they are now. This is a very old technology that is outdated now but, at the time, was quite amazing. It makes me wonder if the 2 side panels are detachable or are they permanent.
