World's Faire

Today I went to the World's Faire which introduces many new advancements from all around the world, invented in around this time. These are some of the things I was fascinated by and learned a lot from.

1. Tractor. 

This was interesting because apparently, it makes farming easier and agriculture is obviously a big part of our world right now. It stated that it could be used in agriculture, construction, and road building. The source that powers this huge machine that moves on its own, is called gasoline and John Froelich from Iowa invented it. It must have been all those vegetables in Iowa. There is also a "track-based model" and "wheel-based model" which I'm not quite sure what they are but they sound like different types of tractors. 

2. Hot Dogs.

This is a type of food invented by the Germans where they put sausages in buns. The name sounds odd for a food but fortunately there are no dogs involved in this process. It was originally sold in New York and it became very popular after the St. Louis World's Faire. 

3. Cotton Candy

Another food that greatly captured my attention was the cotton candy. This was very interesting to see because there was a pile of regular sugar for one second, then it turned into a spinning soft cotton which was edible. There is a machine that rotates the hot sugar into little threads and binds them together onto a huge bundle of thread sugar onto a stick. 

4. Telegraph

This was a way of communication that required no perfect weather. It contained lines and dots that represented different words and sentences, It had to be read by a special operator. This was invented by Samuel Morse.

5. X-rays

These systems helped to find diseases earlier and increase general knowledge about different diseases. This also lead to blood transfusion and advancements in surgery because they could now know what was wrong.
