BR_Uncommon history of common things
Phosphorus: Boiled urine trying to make gold. Makes matches. Phosphorus bullets in WWI to blow up Zepplins in the sky! Also makes incendiary grenades in WW2.
Nickel: Makes stainless steel. [think the Arch] Earth’s core full of Nickel, iron and gold. [MN: Enough gold to cover all land areas of Earth to a depth of 12 feet.]
Quicksand: Cannot sink past our waist. Because your body is bouyant. To escape slowly spread your legs and bring them to the surface.
Rubber: Vulcanized rubber was used to make condoms in 1843. Way before used to make tires.
Asphalt: (Black top) Was used to make roads in Mesopotamia in 625 BCE! Sharp stones and asphalt makes up 90% of our paved roads today.
Heart Transplants: Today transplants average another 13 years of life. Back in the 60’s, they only lived a few months.
Polar Fleece: Polyester: Uses about 25 soda bottles chopped up and heat pressed into fabric.
Counterfeit: They bleach out a real $1.00 bill then scan and print a $100.00 bill on it. Looks and feels real, but does not have the 3D ribbons of real bills.
Pergo: Laminate floors have four layers. Bottom two layers are the subfloor and third layer is actual photograph of real wood. Then top layer is waterproof and scratch proof wear layer. Wood is fused at 600 psi and heated to 400 degrees F. Then it is cut into planks with tongue and groove edges.
Jarvik Heart: 1982: Kept recipient alive for 112 days.
Chameleon tongue: Folds internally like an accordian. Tongue can unfurl to almost twice the body length of the Chameleon!
Shark teeth: Some sharks can go through 30,000 teeth in their lifetime. Teeth are embedded in a membrane, not a jawbone.
Tiger stripes: If you shave a tiger, he still has his stripes on his skin!
Hippo: A hippo can out run a human by running 20 MPH.
Humming bird: Flys forward, backwards and upside down! Can reman airborne for 22 hours. Can fly at 30 MPH.
GPS: We developed GPS in the 1960’s. It was reserved only for military use. In 1973 we built the technology, but commercial usage was a watered down version. In 2000 when it became declassified, commercial businesses were allowed to use the full program, resulting in GPS becoming 10 times more accurate than the crippled program they started with. Until the 1700s we only knew what half the Earth’s surface looked like.
NOTE: After an airliner that strayed into Soviet airspace in 1983 was shot down, the U.S. declassified GPS for the public.
Location tagging: To locate land, the Vikings would release a bird. If it didn’t come back they knew land was close by.
Bluetooth: Named after a 10th century king, Harold Bluetooth who united warring factions the same way Bluetooth connects [Unites] different devices.
Online maps: During the Civil war both sides used hot air balloons to draw battlefield maps.
Pedometer: Thomas Jefferson invented one and released it to the public. He never patented it.
_DR__Deer and Mouse Amazon Video_
Deer:
Has poor eyesight,actually almost blind by human standards. A deer cannot see us in human form. The deer would only see us as a vertical line standing on the ground. Cannot see in color.
But the deer has a smell ability greater than bloodhound and super sharp hearing. Deer can have babies at nine months old!
_DR__The Mouse Amazon Video_
The mouse can squeeze through any hole a pencil can. 7,500 mice are captured and eaten in a typical year by a single fox on the average. Mouse is almost blind and uses whiskers for navigation especially in the dark. Mouse has super hearing ability.
Mice are almost non-stop nibblers . They have a huge metabalism compared with humans. Their heartbeat races up to 700 beats per minute. In just two years they overtake a 70 year old elephant in both breaths and heart beats!
What a mouse eats per day compares to a human eating more than 80 boxes of cereal. A mouse shits about 18,000 pellets per year.
The typical barn Owl can catch a mouse in complete darkness using only their ears to zero in. A snake zeros in with its sense of smell. Mice use their tail for balance while leaning and reaching in their search for food.
The Owl can see 100 times greater than humans!
