"a pan of ice"
probably the weirdest thing i heard in this video
Yeah, a pan of ice and fire. HBO is thinking about doing it as a mini series but totally fucking up the 8th and final season.
@@targuscinco LOL
As the saying goes
What spins around goes around
Nice user name
Bruh
😂 Bro why
Just like the blades of a ninja
ANOTHER THING RELATED TO THE SERIES “PAC-MAN AND THE GHOSTLY ADVENTURES”
The bird inside the egg be like "The wheels in the bus goes round and round"
😂
More like "WHAT IS GOING ON?!"
That might be egg of a snake 🐍
I'm gonna tell him
why are the wheels in the bus? shouldn't they be outside the bus?
I always learn something new from your channel. This one hit home with me! This one, and the forever spin top too have peaked my interest. Amazing!
Can you kindly explain what you understood from this ? In a way i was not able to. Because to be honest he didn't explain anything related to physics at all.
“The center of mass of the egg is the center”
“Ah yes, the floor here is made out of floor”
The center of the floor is the center of the floor
The center of the egg is the yolk
no most objects don't have their center of mass at the center. This only holds for symmetrically mass-balanced bodies.
Indians are pro at spinning traditional tops, miss my childhood. It is still practiced.
:')
Yes brother
Also pro at street defacation
@@diobrando5415 you are pro at it I think as you directly talked about it , may be it is your strongest aspect
@@diobrando5415 Looks like you've a lot of experience watching them. What were you doing ? Looking at it, practicing and learning ?
A spinning top is not just a childs toy. in the sense that it helps to have a PhD in physics to figure out how it works. Besides, some adults DO play with spinning tops (check the web), and some make very elegant ones (see). A spinning top is remarkable because it tends to defy gravity while it is spinning. If spun fast enough, a spinning top will rise to a vertical position and happily stay there, despite the fact that it will fall over if it stops spinning.
A spinning egg is just as amazing. If a hard-boiled egg is spun fast enough it will rise up and spin on one end. A tippe top does something similar, but is even more spectacular. It turns itself completely upside down and ends up spinning with its peg underneath the sphere that was originally spinning underneath the peg used to spin it.
The basic physics behind all these effects is that a torque is required to rotate an object. The torque is equal to the rate of change of angular momentum. There is nothing magic about that. It is the rotational equivalent of what happens when an object accelerates along a straight line. In that case, the force on the object is equal to the rate of change of its momentum. Angular momentum is similar to linear momentum, but it refers to motion in a circular rather than a straight line path.
Usually, the torque acting on a spinning top is just due to the weight of the top. If the top is perfectly upright there is no torque acting on it but if it leans sideways then it will tend to fall over due to the torque about the bottom end. It will indeed fall over if it is not spinning. If it is spinning then it does something else. Instead of falling down, it �falls� sideways. That�s the amazing part. The effect is described as precession, and is explained in simple terms below. A spinning top precesses slowly around a vertical axis through its point of support while it spins rapidly about its own axis. The usual �explanation� is that the change in angular momentum must be in the same direction as the torque on the top - that is, in the sideways direction. The spin axis must move sideways instead of down, but that is just stating the observed facts in fancy technical words.
I didnt notice how long did i type .... Just went keep on writing
Hoping for action lab to reply my comment
As a matter of fact, I have some toy tops of my own, they are called Beyblades!
You’re very fun to watch, sir. Always entertaining and informative. Of all RUclips channels, you are definitely one of my most consistently enjoyed ones.
I remember seeing this in a VSauce video. Seeing this here again is a treat as well. Great one TAL
me too

@@rosynguyen9075 the action cab??
Nvm he edited it
@@iZetto1 I wrote TLA instead of TAL. Then he corrected me with the wrong word. Everything was a mess lol
Really you do what you said "one experiment is worth 1000 expert opinions." Thanks a lot action lab for teaching us in such a wonderful way.
This is alot like how orbits change when thrust is applied perpendicular to the orbital trajectory, 90 degrees ahead and behind will raise or fall depending on thrust direction changing an equatorial orbit all the way upto a polar orbit.
The good doggo approves of this
Another nice job. Keep them coming brada!
friendship with Beyblade ended, now Topsy Turvy Top is my new friend.
NO BEYBLADE FOREVER
I pretty much watch all your videos. I look forward to them. I love the science and the novelty!
This is cool. It reminds me of a video on another channel where they describe the force on a charge in a electromagnetic field and how the result is the charge travelling a circular path.
I've seen another video on the egg portion of the video and they talked about angular momentum but they never talked about how you need friction for it to work. Nice video!
Awesome work my dude 🙂
the chik in the egg: *screaming*
Fantastic brother, your explanation is great and you make people happy
I remember this toy from V-sauce
ايه ده جالى فى الاقاراحات

"You spin me right round baby right round like a record baby right round round round".
Great video and explanation as always. Have you or could you do an explanation video on the process by which a spinning gyroscope somehow loses weight?
love your videos
That was so simple and it took me this much time to learn this fact!
The concepts involved in spinning objects are not simple, and many are counterintuitive.
I love this channel.
GREAT EXPLANATION SIR.
Thank you so much.
As a follow-up, perhaps look at the physics which causes some items to spin stably with their centre of mass as high as it can be.
I have a ring, with a stone in a claw setting, whose centre of mass is heavily biased towards the stone. Whatever orientation I initiate a spin from, it always ends up spinning with the stone uppermost.
That was really interesting, makes sense why is the top would upright itself
I just bought a top and this video came at rhe perfect time!
That's one Interesting Toy! 🤔
Wow what a practical example
I actually loved it 🤩👍
Huh I always thought it was from force of the spin making the opposite side of where it was pushed rise back up (somewhat hard to explain without visual aid). Because of the tilt, the spin would be directed slightly upwards continuing to correct itself with each "throw" until it comes to rest completely upright again. Interesting video glad I know what really causes it now lol. Thanks!
I love these videos.
My school is starting this week, but I started learning today 😂
I had this question from years!!!
Memories flowing
I've observed this in Beyblade with ball shaped tips (conical tips do sometimes do this as well but they aren't a perfect cone that comes to a defined point usually).
Interesting again! Where do you get all your ideas from?
Great video
As someone who grew up obsessed with beyblades, for once i knew exactly what is going on right away.
You spin me right round friction right round
Potential energy right round gravity right round
Imagine being an embryo in that egg and you go on a crazy top-spinning experiment. Talk about vertigo.
You learn something new everyday
This is soo amazing
Gyroscopic precession is taken into account with helicopter flight controls at the hub. You can see the input that pushes and tilts the rotor head is offset.
This is something I'd expect to see on grand illusions
Your channel is really giving much more knowledge than any school or school textbooks.........
Never Gonna leave your channel, sir.👍
Speaking of spinning tops, I was wondering about the science behind the concept of spin stealing in Beyblade. I never quite understood it but it looks very cool.
So can we say that the normal reaction is non-uniformly distributed which leads to non-uniform frictional force at different points which produces torque to counter or even outforce the torque due to gravity along the rotation axis. Hence lifting the top.
I like this man very much
what a coincidence. i was thinking about ding topsy turvy video just before i got reccomended this video
I'm more impressed that you were able to spin that egg
It so cool i need it!
When you learn Science and still have fun:
My teacher should try like this tutorial... she can go home early to finish her class with 100% student understood and happy with your class 😍☺️
This is very amusing
Out of all the forces possible I wasn't expecting friction to do that, even though I knew that beyblades wouldn't spin on the platform covered in ice
Mah dude I'm one of your fan in facebook and I just realised that you have RUclips channel
I hoped you had explained the vector component thing.
I learned about the 90° out of phase with rc helicopters. To move forward, apply lift right side of the rotor disc if spinning clockwise.
Sir can you demonstrate and teach something with gyroscopes please
Hi! Here's an idea for a new video! Inspired by the latest Veritasium video. As I was trying to understand how that contraption works if it works at all, I got quite submerged into sailing and wind speeds. So, when I was trying to understand how come that the apparent wind speed is bigger than the real one, if boat travels perpendicular to the real wind, this idea came to my mind. The wind, that blows from the front of the boat, comes from the energy, stored in a kinetic form, of a wind that blew previously. So we can say that it is sort of the "wind from the past". And apparent wind is a sum of the actual and former wind. Simple, but a bit mind blowing concept, if you think about it :D
I remember having a plastic-thin propeller like top which would spin on ceiling for a few seconds
This is how Gyro actually taught Johnny spin
Arigato... Gyro...
too much fun
At 1:09 I'm guessing it has something to do with angular momentum. Maybe a component points straight down?
Edit: well, half correct 😞
Love from 🇧🇼 Botswana ❤️
Connecting the oscilloscope album to an oscilloscope
1:26 : ah yes the floor here is made of floor
1:30: ah yes the floor here is made of molecules aligned in such a way that it is a solid.
This is how I test if a hard boiled egg is done if it spins upright
Fun fact this is what they use on warships to keep them stable
This guy does short videos but smart videos And this toy really really cool 🤩🤩🤩😊😊😊
Hello Action lab buddy
I wanted to know experimentally that if boiling point of water increases with increasing atmospheric pressure than
What will be its boiling point in vacuum?
I did this with a spaghetti squash the other day and was wondering what the heck was happening!
I'm actually amazed that people like him are on youtube, I mean there's mark rober, veritasium and more, like wow
moment of inertia can be used to explain easily
You could be the new Mr. Wizard!!
increible 😮
Watch some part of it in 0.25 speed he will look like he's drunk
If you attach a magnet to the top, when you attract it will it go towards the magnet or 90 degrees off?
I would show this to my younger brother
good science experiments
Conservation of angular momentum translates to pressures that right the top.
This is actually why actuators on helicopter main rotors are angled 90 degrees from the movement you want to get from them =)
you just explained the simple physics by which the military has used to operate antigravity craft for decades.
Will you cross upload to lbry/odysee?
Hey :) Nice video dood :)
this time i got short on explanation, i didn't quite get it, better a second part
I want to buy it 😅.
Quick question does it matter which hand you use to spin it for that opposite thingymagic to happen?
Action Lab SHORTS!?!?! Sheesh... the clothing options are endless.
if you hold a weight vertically it would seem heavier but when you swing it back and forth the weight becomes lighter because the gravity can't force it because it's Centre of mass is not stable but you would feel the weight's pressure on your shoulder's top. Like this phenomenon so what if we use anti-gravitional force then can we float?
Can you put a solid block of normal ice in the vacuum chamber?
Sir, I want to understand why a rolling wheel can balance vertically and not a stationary wheel? Could you please explain it practically?
"This should be weird to you"
The egg:why you bully me🗿
