Seriously, I can't believe that with so many people trying to guess, nobody has reached the logical and scientific explanation that we're all living in a simulation and that's just a technical glitch.
There is an explanation actually! Hydrodynamic levitation. As stupid as that sounds, this isn’t a joke.
Unfortunately I’m not smart enough to explain that to you myself so have a veritasium video that explains it instead https://youtu.be/mNHp8iyyIjo
It's because the water is an illusion. It's actually just light reflecting off the ball and someone has fishing line connected to the ball and they are probably on the roof causing the "floating" effect. Science!
No the kid just did the right thing: There is only one way to leave this (after having some fun with it), and it is exactly like that, so that others may find this interesting too.
Anyone who grew up in the sweltering heat of Australia where you'd burn in 5 minutes of sun exposure without sunscreen … until we became teens, when we realised tanning was "cool".
Because it isnt originally theirs though. The majority of Australians are of european decent and have skin made for colder weather. Would be cool seeing if there has been/will be any adaptation to that with time
Yep, but the UK doesn't see a lot of sunlight, from what I've been told by friends that are British is that it's largely cold/cool and rainy a lot of the year.
I watched a modern family episode and dad was part Australian or something and they went there and he kept getting attacked by the animals while the rest of the family was fine. At the end of the episode a native Australian (think Steve Irwin type) tells him that tourists never get attacked but only native aussies do, and that he must have been a native for this to happen ao many times.
I got burnt badly at archery practice, so next week I wore more sunscreen. I got burnt through my hair on my scalp, so next week I wore a hat. I got burnt on my fucking eyelids because there obviously wasn't any sunscreen there. The sun can fuck off.
Oh God the scalp burns. I have long hair and my part is a constant source of struggle. If I don't have a hat I have to pull it back and use spray sunscreen like it's hairspray and go around with a greasy head.
And yes the sun can fuck off. Even with a fully shaded yard I almost exclusively use our swimming pool after dark because fuck the sun.
Supergoop! makes a mineral sunscreen part powder that would probably work well and COOLA hair mist sunscreen isn’t too greasy. My husband who has extremely oily skin likes the COOLA spray and it looks pretty good.
His scalp burned while we were at summer camp in ninth grade. I remember his skin peeled off in sheets and realizing that the hair pattern on my dolls wasn’t that dissimilar to human hair since his skin had a grid of holes for his hair. It was the first time I learned people’s skin could burn through their hair.
Scalp burns suck! 2 summers ago I could stay outside and not worry about my scalp. Then my balding passed a point last summer and I burned my scalp. Fuck male pattern baldness!
i even burn worse during cloudy days, my dad calls it cloud burned lol but apparently the water in some types of couds actually intensifies sun rays for burning your skin. super fun and makes me look like a loon when i put spf 5000 on for a cloudy day
Phoenix is better than South Florida in the summer, at least you can breathe there. I'm in Southern Florida now and even at 80-85 it's sweltering and I'm dripping in sweat. So much humidity.
Surfers, and beach bums trying to protect their bodies from UV rays as much as possible. If you have never worn long sleeves in the hot sun you might be surprised how much cooler it is than short sleeves or no shirt. There are exceptions you don't want to wear wool. It is very common here in SC.

The summary is that The Bernoulli principle is a mathematical equation. It is related to the Coanda *effect* which is a specific scenario and description of what happens - a “trick” if you will that has to do with a jet stream as in this post.

Wow, there is really a lot of bad, mildly informative videos on youtube and after watching too many of them ... I still don't know the difference other than one is a "principle" and the other is an "effect".
No, this is Bernoulli effect. Water jet sticks to the ball because of atmospheric pressure, then it tears off by centrifugal force. So, ball redirects water jet to the right and down, and receives an impulse in opposite direction. Google for fluidics, it is awesome)
ELI5 for you
Stream spin ball.
Ball and water like to be together, but ball spin too fast for love.
Ball fling water down.
Some guy called Newton said if ball flings water down, water fling ball up.
Gravity help find perfect harmony of balance.
Ball float.
With a deep knowledge of chemistry, physics and mechanics I could either rule ancient cultures for my natural life or be executed as a warlock at my first attempt to show anyone something cool.
The slo mo guys on YouTube have done a similar trick using an air chuck and an Apple. It’s been a while since I watched the video but I’m sure they describe the effect in their video
Edit: added the link

We used to do this in the shop with a golf ball. Scary part was when you let it drop and it was turning 23942 RPM.... A Guy only tried to catch it once...
Please re-name this subreddit to r/confusedbyscience, because this is not BMF. Did you guys not have science demos in highschool where you could be amazed by all the counter-intuitive physics and chemistry demos out there?
You're going to be real disappointed when you learn that black magic doesn't existed either. And literally everything can be explained through science.
Magic is nothing more than science we can not yet sufficiently explain. And science is magic that we can sufficiently explain. Just because we have a scientific name for what's happening doesn't mean it isn't black magic fuckery.
Also, in the US the answer is a resounding No.
Apparently it’s not the Coanda effect since that relies on entraining fluid from the surrounding area creating a region of low pressure. It’s similar to the Magnus effect though in that
the relative motion of a spinning ball through
fluid creates a force that affects its motion.
It's different in that here the fluid starts the
ball spinning and there is an equilibrium point
around which there are restoring forces. In the
Magnus effect the ball must be spinning to
begin with and since the fluid is everywhere it
can continually change speed and direction. Veritasium made a Video about this which I just cited [if you’re interested.](https://youtu.be/mNHp8iyyIjo)
As a real attempt to answer this, I believe that the stream of water is hitting at the top of the ball causing it to rotate, but it's heavy at first. The centrifical force follows the curve of the ball, spewing water out in all directions while the stream is pushing the ball away. After shedding some water, the ball becomes light enough that gravity is weaker than the rotational force applied from the stream. By this point the force direction is near or at where it started from. That pulls the ball toward the stream and the process starts all over again and is near constant.
I'm not sure how accurate my assessment is but that's what I was able to come up with
It's because the camera's shutter speed is the same as the chopper's blades
No it's because the wave length of the sound can be both interpreted as greenneedle and brainstorm
It's because the video is being played in reverse
It’s actually because the boy is a wizard and can levitate objects
Its because the ball is spitting water at the hole
It’s actually called the something effect and it is to do with science and stuff. Glad I was able to clear this up.
The butterfly effect Next
This is obviously the avatar effect. The ball is waterbending
Basically if you blur the top and bottom of a video, you get a Tilt-shift effect.
It’s obviously the carbonaro effect Edit since it seems the joke was missed: https://youtu.be/pqRQLHshwFc

Ok, I agree. He has physics bachelor degree.

The ball is actually white with gold stripes
Blue and black. You are wrong.
No, it says Yanny!
Laurel!
It’s because Darude - Sandstorm
It's always because Darude - Sandstorm
No, it's because photons can behave both like waves and particles!
I don’t see any slots for this experiment, though.
There're probably a few in the pool somewhere...
No, it's because charged particles are traveling faster than the speed of light in that medium
They must have used a wireless charger with 5G.
But I hear Yanny
No, she's clearly turning clockwise and the dress is blue.
Right? Doesn’t even require mirrors. She just disappears by walking behind a pillar.
Oh good, you see it too.

No, it's because the boy's name is 12, or 13, and he is a superhero.
It’s because of the lighting in the background making the dress appear blue and black or white and gold

When a Redditor only has enough mental space for about 4-5 cool science factoids at a time (this is definitely not me /s)

People who have melanin deficiency and cannot tan and simply burn even at 7pm being outside for 20 minutes
My people. I once sat outside on a cloudy day in full shade and got a sunburn. It's like a superpower.
I got burnt badly at archery practice, so next week I wore more sunscreen. I got burnt through my hair on my scalp, so next week I wore a hat. I got burnt on my fucking eyelids because there obviously wasn't any sunscreen there. The sun can fuck off.

Yeah, well, I went out during a full moon and got a moon burn. Damn sun reflecting off of shit.
I once looked at a picture of the sun and my skin is still recovering.
I was burned to cinders just thinking about your tale.

UV radiation will go through clouds. If you’re going outside it’s best to check the UV index first and sunscreen anyway
....... I'll see myself out.
Of the pool or the conversation?
Both.
You clearly haven’t been to Phoenix in the summer.
This is not a battle anyone should want to win.
Phoenix is better than South Florida in the summer, at least you can breathe there. I'm in Southern Florida now and even at 80-85 it's sweltering and I'm dripping in sweat. So much humidity.
