Did you known that today is CREATE A VACUUM DAY??
It's a weird day for pets as our families NEED to vacuum but that vacuum is A WEIRD DEVIL THING.
Let's talk about the history and science of vacuums!
#CreateAVacuumDay
Back in ancient Greece, some scholars thought vacuums were just a myth!
One philosopher, Democritus, saw things differently.
He believed there was a void between atoms and referred to it as a vacuum.
Fast forward a few thousand years to Galileo Galilei.
Galileo's pump makers told him they could only pump water to 30 feet, but couldn't pull it out of a well more than that distance.
His student Torricelli, had a brilliant idea!
They switched to using mercury, which is 13 times denser, and found that when they filled a tube with it and placed it in a dish, the mercury dropped by 0.39 inches.
This showed that a vacuum had been created (and later a unit to measure vacuum's was called a Torr!)
Vacuum Examples!
Have you ever been on a plane and noticed how your ears pop as the plane ascends or descends?
That's because the air pressure is changing due to changes in altitude.
Did you know that there's no air in outer space?
It's close to a perfect vacuum, which makes it a unique environment for astronauts to work in.
It's also REALLY dangerous as any hole in a spacecraft causes AIR to rush out into that near perfect vacuum.
The next time you use your smartphone, think about this: it uses vacuum technology to keep dust and debris from getting inside.
Microprocessor chips are also built in a vacuum to create an environment free of impurities!
That's a wrap!

Dogs are pretty awesome.

If you ask someone who has a dog who their favourite person is, they will laugh and tell you that it is probably their dog.

BUT - here is something that will blow you away.

A new study found something amazing about dogs.

Read on.

Dogs and Kids go together like well...peanut butter and chocolate or peanut butter and bananas or well ..ok peanut butter kinda rules.

Dogs rule too.

In school, dogs have been shown to lower anxiety, improve reading, and improve empathy.

This study found something else. Image
There is this assessment test called the BDI or Battelle Developmental Inventory.

This test or assessment breaks down if kids are making developmental milestones.

It isn't a random survey, it involves trained professionals watching kids or getting data.

What makes a dog so friendly?
Is it training?
Is it the breed?
One theory is....love.
Find out why on The Super Pawesome Science Thread!
#TSPST a spooky dog in a sheet. Just kidding he love you.
This story and theory are from the book Dog is Love by Dr. Clive Wynne (@caninecognition) and research by Bridgett vonHoldt.
Shoutout to the scientists that made this wholesome thread pawsible!
Let’s get into it!

@caninecognition Science is pretty unanimous when it comes to dogs.
They are unique in how they interact with humans.
A good many scientists feel dogs can understand us in ways other animals can’t.
They can follow a point and hold our gaze.
This is coded in their DNA. a puppy looking to the up and left with a setting sun behind her

A fluffy giant puppy was the happiest thing in our lives.
One day he had an injury.
Everything turned out ok but we learned harsh lessons.
We hope this story gives potential pet owners some advice. This is a photo of a little baby Berner he is looking up to the camera with expectations of love
Bunsen was this adorable, happy puppy.
Every single day was the BEST day of his life.
He was adventurous, always smiling, and attracted a crowd.
Then he broke his toe.
Badly. A X-ray of a dog foot
To this day we don’t know HOW he broke his toe.
He just started limping and crying.

Hey!
Can you tell if you cat is happy?
YEP!
Here are FIVE ways to tell if your cat is happy!
--THREAD--
1. What your cat sounds like!

If you’ve ever had a conversation with your cat, it’s a sign that they are happy!
Sure, they may be DEMANDING things of you, but it shows they are content and comfortable to be vocal with another species! A cat on a turtle
While the pitch of a meow is TOUGH to make a conclusion about, a higher pitched meow is associated with a happier cat, while a low pitched meow could be annoyance or frustration.

Beaker is our Golden and she is the sun on a gloomy day.

She is the hope when days are tough.

Her smile turns any frown upside down!

Here are ten amazing and fun facts about Golden Retrievers!

🧵
1. Natural Swimmers: Golden Retrievers are excellent swimmers with water-resistant coats and webbed feet, making them superb companions for water activities like swimming and retrieving.

As a puppy Beaker swam at least 1km in a mountain pond and got into another kayak.
2. Social Butterflies: Known for their friendly and sociable nature, Golden Retrievers tend to get along well with people and other animals, making them popular therapy and service dogs.

Beaker loves every human with the force of 1000 hurricanes. Image
