Momofuku Ando is a national hero in Japan, for helping to end a national food shortage after World War II. He did this by … inventing instant ramen. He created the brands Top Ramen and Cup Noodles.
At the time, the United States was providing wheat flour to Japan to prevent widespread famine. The Japanese government tried to encourage its people to make the wheat flour into wheat bread, but that was unfamiliar to pretty much all Japanese at the time, and many went hungry instead. Ando thought noodles made more sense. Noodles were familiar, could be made using wheat instead of rice flour, and could be easily made at home using only hot water. After months of trial and error, he debuted the first instant noodles: Chikin Ramen. And the rest is history!
Since 1219, Estonia was ruled at various times by Danish, Swedish, German, and Russian governments. It declared independence after World War I, but that only lasted until 1940 when it was occupied by the Soviet Union. Estonia has only been an independent nation since 1991.
That means that since 1219, Estonia has been independent for exactly 50 years out of 800!
Duct tape was initially used during World War II for a very specific military purpose: keeping ammunition boxes sealed. It quickly became clear that it was useful for many other things, as well. And its incredibly adhesive qualities as well as inherent waterproofing led to soldiers calling it “duck tape,” referring to a duck’s wicking feathers.
After the war, former American soldiers who went to work in construction spread the word about the amazing new tape. It ended up being used for all sorts of HVAC applications, but mostly for holding ductwork together, so “duck tape” became “duct tape.“
During Word War II, the Imperial Japanese Navy used Kaiten submarines, which were the torpedo equivalent to kamikaze pilots. Kaiten subarines were manned torpedoes that would engage in suicide attacks on enemy ships.
They were relatively ineffective and there are only three confirmed successful kaiten attacks in the Pacific theater.
