Trick or Treating has been going on since the late 19th century. The tradition started in Scotland when kids went to mourn the loss of the dead and keep them away by dressing up like them to get food, such as cakes and fruits and sometimes, they even got money! So, why do we say the phrase "Trick or Treat"? When kids used to go around in Scotland, they would ask for treats. But, if they didn't get any treats they play a trick on the owner of that house. Nowadays, Trick or Treating on Halloween (October 31st), is a thing everybody looks forward to every year. Halloween is a holiday shared by everyone with costumes.
Ever since Galileo first discovered the stars 400 years ago, we have been trying to find galaxies other than ours. The Hubble space Telescope discovered the Ultra Deep Field (otherwise known as the UDF) in 2003 and 2004. But there is a place right in the center of the UDF called the eXtreme Deep Field or the XDF. In the XDF, there are more than 5,500 galaxies! This gives Scientists the best glimpse of the history of the universe's history. Astronomers believe that the XDF is 450 million years old. Who knows what they will find out next?
What the XDF looks like: Hockey pucks have been used since 1875. Hockey pucks are made of rubber and are only made in Canada, Russia, China, and Czech Republic. 5,000 pucks can be made in a typical week. Hockey pucks can reach up to 100 mph or more! Sometimes, the team's logo is on the puck. Hockey pucks are kept frozen to slide on the ice faster. Hockey pucks are super cool.
What a puck looks like: What do you think an Aerogel is? Hair gel? A Crayon Color? Well, Aerogel is neither! Aerogel is the lightest solid man-made substance ever! Who invented Aerogel you ask? Well, the answer to that question is Samuel Kistler. Him and a another inventor named Charles Learned had bet on who could make a substance like gel with replacing the liquid with gas while keeping the structure of the gel together. When it was finished, Kistler proudly named the substance, Aerogel. Aerogel can go for $23,000 per pound, so the reason why you probably haven't heard of the substance is because of how expensive it is. Aerogel can suck up and separate water, gasoline, and oil. Aerogel can become red in 90 seconds if you put the Aerogel in water with red food coloring in it. So that show how cool and expensive Aerogel really is. So with that, I am finished with talking about Aerogel. See you next time!
A picture of what Aerogel looks like: Although most people think that a Zebra is a white animal with black stripes, scientists have discovered that Zebra's are actually black animals with white stripes. Scientists used to think that Zebra's have stripes to camouflage against Lion's, who are color blind. But since they came up with that theory, they have since dropped it because other African animals have not developed stripes yet. They now think that Zebra's stripes deter flies and keep them cool in hot weather. Flies that carry disease's hate landing on stripes, so it will deter flies. The air will swirl around the stripes to keep the Zebra's cool. Zebra's stripes are cool. Literally!
Iron man fans, rejoice! Tony Stark's suit is a reality! Daedalus Mark 1, as it is called, was made by 38 year old Richard Browning. He set a Guinness World Record with the suit. The fastest man controlled flight. Iron man fans can get in on the action in a simulation of the flight. That is really cool!
In 1878, a man named Eadweard Muybridge made a brief moving picture known as "The Horse In Motion." A California Senator named Leland Stanford asked Muybridge to settle a question with technology. The question was "When a horse runs, does it have all four hooves on the ground?" Muybridge used multiple cameras to film a horse in motion. He then turned the pictures into a stop-motion movie. The answer to question was, yes, a horse does have all four hooves on the ground when the horse runs. So thanks to Leland Stanford and Eadweard Muybridge, movies were born.
