how many volts is this inducing

So if i pee on a lightbulb, the light will totally internally reflect all the way up my pee stream and illuminate the inside of my bladder?

Correct me if im wrong, but i was wondering why the pendulums line up exactly in that formation. What i think is because of the different string lengths, each weight moves a different distance, and because of that, they offset slightly to make those patterns

Cool. I wish you explained more about the gel and the constituents of the gel. What are the properties of each chemical by themselves? Why do they gelatinize when they are mixed together? I feel like a lot of the interesting science was omitted from the video.

Got canned heat in ma heels tonight baby!

Nice one. Now how is calcium acetate made?

He just only do experiment he save my life

Would that sound different if the horn was in the back of the car? In a way I know it wouldn't but it seems like it would at the same time. So....???

That is soo coll. I could watch that all day.

I also came after arvind sir class

I feel like I'm watching the off day of a mad scientist villain when he's not busy trying to hold the world hostage.

Tumfrico's Period Experiment. Amazing!

Beautiful

The girls at Harvard really love playing with those hub

it must be just aluminum burning in air, the friction heats up tiny aluminum particles to +1000C and it burns in air, there is no rust mix in aluminum with enough spread to call it thermite reaction. a scientist will try all possibilities before taking a conclusion, dissolve the rust with HCl and dry the ball to have same matt/rough surface without the iron oxide and repeat the experiment.

"More imaginative" thats a polite way of putting it lmao

I’m itching so bad to joke about them slapping balls together, but I’m going to resist it as best I can.

1:25 You can never “Went to go...”.

sunsets with a lot of ash in the air are quite red.

How can he just make a demostration video like a form of art

So, rusty tools rattling around in a toolbox with some aluminium foil could ignite an oilly rag! Potentially. Thank you. ✌️

Very cool idea. Really neat.

Wow sehr interessant 😮👍👍👍

This video, without any words, helped me exactly understand blackbody radiation.

I just wanted to know if your mask protects you from radio waves........

Rock banging based technology is the best

Do it at a petrol station now

I remember chinese fireworks like this. They called them dragon balls. Hit them together theyd spark.

Melting skyscrapers

I love stories from Harvard Natural Selection High School.

Too heavy to replace normal hiking ferro rod.

👍👍👍

I wouldn't trust the antisemites at Harvard about anything. They have NO credibility at all. This whole demo is probably fake to show how black metronomes have more rhythm than white ones.

I dont know if that's actually a thermite reaction. I think it's not. Steel balls hitting each other will heat and compress the air between them, creating a shockwave. It works with clean balls and paper too. In this case, it very well may be simply burning the molten base aluminum in the oxygen in the air, and blowing off a tiny bit of iron oxide. Considering the velocities of air, i would be very surprised if the two had a chance to react with each other. Frankly, it would look about the same since either way oxygen is bonding to molten aluminum. In fact, the air oxygen would be MORE energetic since it doesn't have to rip off of an iron. Prove me wrong. I'd love it if this was actually a thermite reaction. Blowing up thermite doesn't usually make the thermite react.

DEMONSTRATIONS WITHOUT THEORY ARE PRETTY USELESS. MR WALTER LEWIN COMBINED THEM ;-)

Earth core to the iron ball be like : tum masst kaam kartaa hai, Anand bhaai ! 😊 Lava to the brick chunk be like : itney mey hi pighal gayaa, chhotey ?! 🤨 Kyaa sochaa thaa, sardaar khus hogaa, sabaasi deygaa ?! Al-Si !! 🤧

Remarkable ! Thank you for your time.

"Where should we do the microscale thermite video?" "Let's do it in the gray experiment chamber" "Cool, should I wear gray?" "No, blue."

That's why in Australian coalmines they don't use alluminium underground in general.

I would have never come up with this idea, although it is so obvious watching from backwards, of course. Thank you!

I often have problems with Aluminium oxide collecting on my balls too. I find a liberal application of talc can help with that.

She has balls

Great...( 0.1)^4 times 16 is equal to (0.2)^4 I like it

thanks for demonstrating

Better than the entirety of Aggro Dr1ft.

How many students have smashed digits with a poorly-aimed blow? As for determining if it is actually a thermite reaction, I'd try using a couple lumps of a different oxidized metal, perhaps copper for a nice bright green flash, but the copper may not be hard enough to cause a reaction on impact at reasonable speeds.

I bought two large bearings at a farm rummage sale so I could do this. It took years to rust one bearing. I gave up and threw it into the wood stove. I took it out in the Spring with a good coat of rust forming. Sparks good!

So, what you're saying is: "Physics is a matter of perspective"...? 🤨

I came here to explain my job to people, and now I have to pee.
