So this is what is happening in the world around us all the time, yet we can't see it... What this experiment has done is make the invisible become visible and more understandable. You know... you can study electronics and physics, and hear about the right-hand rule, Lorenz, etc. but when you _actually_ see it in action is when it becomes real. Thank you for a beautiful demonstration on the Action Lab!

This guy is having so much fun in quarantine and we are here watching this vidio and looking through comments

That is so cool, such a beautiful experiment, thank you for sharing this.

*Wish this Mark Rober type guy was everyones' science teacher.* Instead we get uninterested people who keep using slides whole semester to teach a course.

I did this using mercury in a closed vacuum toroid, containing nanoparticles of iron barium and cobalt.using coils around the quartz toroid, as you increase the voltage the mixture will spin homogeneously. Then it will lift and center in the middle if the toroid..You can accelerate it much faster since there is no friction against the walls. Eventually the mixture will turn into a plasma. Accelerating it even faster you will get a corona effect. Placing a secondary coil around the toroid, electricity will be produced! Nice demo for a college physics class. Now, I understand that if the toroid is mounted on a base, and suspended by a mechanical fish scale ( to avoid any possibility the magnetic field is interfering with an electronic scale) as acceleration increases after the corona effect, a white glow will appear. At that time you can see a decrease of weight of about 5% ! This was demonstrated at the department of physics at U of Alabama in the 1990’s , but they were initially using rotating discs under a non metallic 100 gram weight weight sitting on a non-metallic platform . First it was thought the 3-5% decrease in weight was caused by wind coming from the Warner drill. The experiment was reproduced with the entire apparatus in a high vacuum glass chamber; with the discs paining outside the scale on the vacuum chamber. This was published in a peer reviewed journal. It was concluded that the spinning discs mounted on a rotating shaft were somehow “interfering” with gravity. 3 months later the scientist accepted a position at Laurence Livermore Lab; no more publications since then…. I just don’t remember the proportions of each element and why Co & Ba were chosen to be mixed with nanoparticles of Fe…. Would love to hear your thoughts on this experiment.

Hi; Would you try to test generating current by swirling the gallium around. Thanks!

This guy is the underrated Mark Rober..

I love how straight to the point this video is

The thing I love about this channel is that almost all of these titles seem super clickbaity and that none of them are true and yet he always actually does it

Your Experiments are so satisfying and I love them!

This seems like the simplest version of an electric motor you could make.

I just love that you come up with experiments you want to do and decide to share it with us. Thank you. ❤️

This man is gonna one day build a black hole on accident

Very cool way to teach these concepts wish someone had shown me this 6 years ago when I was studying all this it would have been very fascinating.

This is amazing, I've always wanted to do this! Some other fun experiments to try: (1) make a loop de loop by using a cup or container with a lid and see if a small amount of gallium has enough momentum to complete the loop. (2) Take a clear plastic container and put flat electrodes on the top and bottom of the container, then use a AC current source and see if you can get a blob of gallium to bounce between the electrodes or (with fine tuning) get it to levitate!

I love this channel, you teach me so many new things every time! keep up the good work

When you're farming for Gallium in Warframe but the Grineer just doesn't want to drop it...

I think you are special. there are many youtube science teachers. you understand it. my understanding comes from your understanding... understanding is so much different than knowing.

THIS is the kind of learning that I watch your videos to see.

Hello sir! I really love your videos, and it would mean the world for me if you made a video explaining quantum field theory (quantum fluctuations, etc.). I have been a a fan of your channel and quantum mechanics for a long time, and to see those two things together would mean the world for me!

love this channel.. keep it up. i learn so much. thanks

I always enjoy watching your demonstrations. You explain things in language the average person can understand. Your like a real life Professor Proton!

I learn more cool science from this channel than I did in any middle school, high school or college level class. Keep up the good work ☆

Man, I wish I had your creativity. Awesome little experiment again!

That was way cool, James. Thank you.

Absolutely BEAUTIFUL

You've come so far it seems like yesterday you were at 100k subs I love to see it

Very cool. Also very cool, did you notice the lead wires moving when the current was applied to the circuit? That was also very cool to see. Thank you for these videos.

Just when I thought gallium couldn't get any better!

I love this channel!

There was also a flight engine to do with this, involves spinning the mass up/down a corkscrew fluted bowl, but it involved Mercury, which makes sense because its heavy? More mass to offset your weight by spinning it in a particular pattern at force.

That.....was...........innnnnncredibleeeeeee!!!!!!!!!!!

This is amazing. I wonder if the inner layer were textured, if that would have an effect on the motion. For instance, small ridges / / / on the bottom plane that the material would flow into.

Nice! This was polarizing!

for some reason this channel is not showing in my home page despite lately it almost always shows old videos that I've watched. I thought you were not releasing videos anymore. Now I need to spend all night to watch all your latest videos.

Yes, we did really love the video !

I think the movement of the wires as the circuit is closed is also very cool

Nice one pale!!!

nice vid! keep it up!

This is something new to learn

I would gladly make that a screensaver. Where it’s moving but you can’t tell. Mesmerizing

I found watching that, along with the music, to be oddly relaxing.

These video maybe be short but very explainable

Am i the only one who loves his work?

Simply beautiful

That was super cool

I wonder what it would do on low frequency AC or even with high power audio signal.

why cant i give you two thumbs up. This is waaay too cool

Real Cool !! 👍👍👍

Gallium is an amazing metal. Safe and fun to play around with.

Why do the wires themselves seem to have some sort of force acting on them when it's just electricity flowing through them?

That's pretty cool that you can change the direction of the spin. **Proceeds to change back and forth 100 times.**

So cool 😍

Perfect experiments

Super!

This gave some insight into Germany's "Bell" UFO craft of the 1940s.

Awesome! U might be the very rich to do such experiments

Magic, mystic, physics. Thank you

"Whoa" that should be on your merch

Thats so cool

Nice, I just received my Gallium (from China) and I will try this with a function generator connected to a waveform amplifier. Gallium is fun but make sure not to keep it in a glass container, because it expend (3%) and could break the glass.

Your big fan brah

Interesting how it will look like on over voltage

amazing

This is basically an invisible impeller... you could make a really convincing "self-filling funnel" with this, with no moving parts.

Woh other noticed the black and Red wires move when he changes the polarity due to the electromagnetism!!

You can also use NaK for fluid.

I want a beanbag made of that.

Interesting. Maybe applicable in some form of control moment gyroscope. You would need to manage the temperature to keep it a liquid (I guess the cold of space would be a problem). Curious how this is currently employed in any devices. Thanks.

Could you try linking it to an amp & play music, I did that to a lightbulb years ago. It not only lit up very dimly but also made sound.

Liquid surfaces for plasma facing components - if anyone is interested how this principle can be used for heat shielding in fusion reactors that are much more efficient then whats currently being developed

Still after all these years you came up something new and cool like this. Where do you get your ideas :DD

I edited this comment so no body can insult my English teacher. 😂😂

You have to do this again but in a vacuum chamber. I’m wondering what it will look like and if the oxidation layer will still form??

Nice video. If all we need is a conducting liquid, would it also work with a brine solution? Or would it not work with Water as it is not viscous enough.?

i wonder how would it react to alternate current, using different frequencies and amplitudes.

So Gallium is Fun Mercury!! 👍

Cooooool!!!

That is cool

Try applying an alternating current too, would it oscillate?

I wanna do this now

Early Cray supercomputer processors used to be made of gallium arsenide and cooled with liquid nitrogen (IIRC).

thats amazing you are amazing

Neato! 🍄

How do you come up with ideas that are more amazing every time?

Make a video on ultrasonic lavitation...it is cool technology and i think that most of the people like to see it .

Woooww;!! I jst studied about this in my 12th physics book🤩🤩🤩🤩... ❤❤

Could be done the same experiment but using "really salty water" instead of galium??

28 people didn’t like this video? 🤷🏻‍♂️. There’s just no pleasing some people. 4k people did like it. I certainly did. Amazing demonstrations.

If you start reducing the ambient temperature can you get it to start solidifying? Having gallium slush might make the motion very easy to see.

It's very cool that the direction of the vortex spin depends on the direction of the electron flow, but why does it? I was curious if the vortex just started in an arbitrary direction, like the drain in the bath tub. I didn't expect the direction to be dependent on the electrical polarity. Why us that?

I wonder what would happen if you used a signal generator instead, varying through very low frequencies starting at say one cycle per second working up. Would there be harmonic effects?

I like the First sentence he is saying in literally every video.

Can you make a closed-loop electromagnetic gallium (or galinstan) pump please?

With a turbine submerged, a simple motor could be made.

That's one self stirring cup you do NOT want to drink out of

Does the magnetic polar surface direction also effect the rotational direction in a similar manner as changing the flow of electrons?

Nice

Been thinking of doing this... You beat me to it... 👍 Cool shit 🤓

So underrated
