Weird Science Facts You Didnt Know
13 Wild Science Facts You Probably Didn't Acquire in Loftier Schoolhouse
We acquire about some awesome scientific discipline in high school - like Einstein'southward theory of relativity, the Periodic table, and DNA replication.
The noesis we pick upwards there sets the foundations for all the other amazing things we go along to study. But science definitely doesn't end at high school, and information technology'southward once you lot take your learning to the next level that things get really interesting.
In no particular order, here are some mind-bendingly incredible facts that we didn't acquire at high school, only wish we did. Because I certainly would have paid a whole lot more attention if my teacher had shared a few of these insights in grade.
Side note: if you did learn about all of this and more at school, so you lot had a kick-ass teacher and you lot should probably tell them that.
1. Water tin can eddy and freeze at the same time
Tenstone
Seriously, information technology's called the 'triple point', and information technology occurs when the temperature and force per unit area is just correct for the iii phases (gas, liquid, and solid) of a substance to coexist in thermodynamic equilibrium. This video shows cyclohexane in a vacuum.
2. Lasers can get trapped in a waterfall
BuzzFeedYellow
Oh my gosh, yep. Non simply is this an incredible example of total internal reflection, it also shows how fibre optic cables work to guide the catamenia of light.
3. Nosotros've got spacecraft hurtling towards the edge of our Solar System really, really fast

Nosotros all know rockets are fast, and space is large. But sometimes when we're talking nearly how long it takes for us to get to distant parts of the Solar Arrangement (eight months to become to Mars, are you kidding me?) it can feel similar our spacecraft are only crawling along out in that location.
This gif shows just how wrong that thought is by comparing the speed of the New Horizons probe, which flew past Pluto last year, to a 747 and SR-71 Blackbird.
iv. An egg looks similar a crazy jellyfish underwater

A cracked egg on state might brand a big mess, but 18 metres (60 feet) below the surface of the sea, the pressure on the egg is ii.8 times atmospheric pressure level, and it holds it all together like an invisible egg trounce. True story.
5. You tin prove Pythagoras' theorem with fluid

Non buying what your maths instructor is selling when they tell you atwo + btwo = c2? Yous can actually prove it with liquid.
6. This is what happens when a blackness hole swallows a star
NASA
As the star gets sucked upwardly into the black hole, a huge jet of plasma is burped out, spanning hundreds of light-years. "When the star is ripped autonomously by the gravitational forces of the black pigsty, some part of the star's remains falls into the blackness pigsty, while the rest is ejected at high speeds," explains Johns Hopkins University researcher, Suvi Gezari.
7. You Tin can see without your glasses
MinutePhysics
According to MinutePhysics, all you need to do is make a pinhole with your paw, which will assist you focus the lite coming into your retina. Sure, it won't give you twenty/xx vision, but it'due south a skillful commencement if y'all've left your glasses at home.
viii. This is how a confront forms in the womb
BBC
Embryonic evolution is an incredibly complex procedure that scientists are still just beginning to empathize. But one thing researchers accept been able to map out is how the embryo folds to create the structures of the human face in the womb. Nosotros could picket this all day.
nine. Popping your knuckles isn't necessarily bad for you
Vox
I researcher popped the knuckles of one paw for 60 years simply not the other, and found no discernible difference in the amount of arthritis between the two of them at the end of his experiment.
Find out more in this video from Vox:
10. A single solar flare can release the equivalent free energy of millions of 100-megaton atomic bombs
NASA
And they're happening all the fourth dimension.
11. Cats ever land on their feet, thanks to physics
Smarter Every Mean solar day
As Smarter Every Mean solar day demonstrated with this awesome ho-hum-mo footage, cats actually use the 2 halves of their bodies separately to ensure rapid rotation (don't attempt this at home).

12. You'd exist better off surviving a grenade on land rather than underwater
Mark Rober
Those balloons? That'southward what would happen to your lungs if an explosion went off near you underwater.
13. If you spin a ball as you lot driblet it, it flies
Veritasium
I mean, information technology really flies. It's thanks to the Magnus effect, which occurs when the air on the forepart side of a spinning object is going the same direction as its spin, which means it gets dragged along with the object and deflected back.
Meanwhile, the air on the other side of the ball is moving in the opposite direction, and so the air flow separates.
Scout Veritasium explain information technology amend than we e'er could:
We could keep going... but the best part about science is that it discovers new things every day. Never stop learning.
BRB... going to become drop a feather and a bowling brawl at the aforementioned fourth dimension:
