    17 Things I Learned This Week That Blew My Mind In Ways I Didn't Know Possible

    It would take how many balloons to lift the house from Up? 🤯

    1. The sea pangolin is a species of deep sea snail that lives near volcanic vents in the ocean and has a shell made of iron sulfide — yes, this snail is made of metal:

    I recently learned that volcano snails exist. Their shells are made of iron and they live around hydrothermal vents that can reach up to 750 degrees Fahrenheit.

    This amazing animal was recently added to the IUCN Red List as endangered due to destructive deep sea mining practices.

    2. In some international versions of Sesame Street, Big Bird is not yellow.

    In the Sesame Street universe, these are technically Big Bird's cousins.

    3. Inspired by Pixar's Up, this is allegedly how many party balloons (30 million) it would actually take to lift a house:

    Originally inspired by a YouTube video created by The Corridor Crew, Reddit user u/Andy-roo77 posted this image and left a comment on the post saying: 

    "In their video they showed how many weather balloons you would need to lift the house. Party balloons are much smaller, and I was still curious to see what 30 million party balloons would look like. So naturally, I made my own estimate on the ruff size, and then made the picture in photoshop."

    4. There's a pink manta ray in Australia — the only known pink manta ray on the planet — and the leading scientific theory for how it got its unique color is genetic mutation:

    A rare pink manta ray was spotted off the Great Barrier Reef in 2020. “I had no idea there were pink mantas in the world” says photographer Kristian Laine. The fish, who cruises the waters around Lady Elliot Island, is the only known pink manta ray in the world. from Damnthatsinteresting

    5. You've probably heard of Balto, the Husky who's famous for leading the sled team that delivered an anti-toxin serum to Nome, Alaska, during the 1925 diphtheria outbreak. What you might not know is that Balto only led the final 55 miles. It was actually Togo who led the sled team during the longest and most dangerous portion of the journey (over 261 miles) — Togo was a whopping 12 years old (!!!) at the time:

    (Here's Leonhard Seppala and Togo pictured shortly before their 300 mile dog sled trip to Nome, Alaska in 1925.)

    6. Marion Stokes recorded live television 24 hours a day for over 30 years. There's a documentary about her life titled Recorder that dives deep into this ambitious project and the person behind it:

    7. The Curiosity Rover used to sing happy birthday to itself every year. It has since stopped because "there is no scientific gain from the rover playing music or singing ‘Happy Birthday’ on Mars."

    8. Someone actually found out their spouse was cheating on them by poking around on Google Maps:

    9. These stunning photos were taken by divers in the underwater city of Shicheng in China. How did the city end up underwater? It was intentionally flooded to make room for a hydroelectric dam in 1959. The city's residents at the time were relocated — some families had been living in the city for generations:

    10. There's a smaller Statue of Liberty in Paris. For the 1937 World Fair, it was turned to face its US-counterpart:

    In Paris there’s a quarter-scale replica of the Statue of Liberty. It’s 22 metres tall and faces west in the direction of its larger sibling in New York City. from interestingasfuck

    11. This is how the plumbing worked in many medieval castles. In fact, these "latrine shafts" were occasionally used to gain access during a siege:

    15. This asteroid orbiting between Mars and Jupiter might be made entirely of metal (iron and nickel). For context, most asteroids contain some metal, but this asteroid might be all metal. If true, it would likely be worth $10,000 quadrillion:

    16. The term "crocodile tears" is an expression used to describe someone who's faking grief and/or emotion. Did you know it comes from actual tears that crocodiles shed after they eat?

    Crocodiles shed tears as a result of the air trapped in their sinuses after eating their prey. So this has nothing to do with pain. For this reason, the expression crocodile sheds tears is used for people who do not feel sorry for something but pretend to be sad. from interestingasfuck

    17. And thanks New Zealand's rapid and science-based response to the COVID-19 outbreak last year, residents have been living relatively normal lives compared to the rest of the world. In fact, they haven't even started administering the vaccine yet.
