1:57 but piano is considered percussion.

Thank you for sharing it

Thank you very helpful.

What a paradox

Physicist of par excellence even greater than Einstein

Think you💚 from atlas🗻 africa🌍.☀️

Awsome ..thanks alot❤

Searched 4 this And got surprised 😮😮

Very nice. great intro about the standard 3 parts of electricity and putting resistance last of the triumvirate, or downplaying resistance. Sticking to volts and amps seems easier. Resistance, seems to be just whatever material or distance. Or current is always some function of Resistance. This seems to focus on getting the power concept, invisible power of electricity, down first, then has a good footing for future lessons about the distribution of electricity which factors in the resistance concept, distance and material and temperature. I got sidetracked about Electricity, is Alternating current, kind of like a way to reduce friction in a water pipe by rotating the tube with fingers. I know HVAC flows better in spiral tubes. I'm still trying to understand what AC is, and how power wants to potentially balance itself, even when it's constantly switching direction. maybe direction is not the way to think of AC, like you said, electrons are already there.

they did not save the tree but cloned it. apple trees don't often live past 100 years and 150 is their limit on this mortal coil. but careful grafting can preserve the legacy of one of humanity's treasures. so i choose to believe that the offspring of newton's tree lives on.

Not bad

I had this as a kid and I had so much fun with this thing

White never existed!!?? What the hell??! Literally, you mean white is an illusion 😨 we made this colour and it actually never existed 😮 👇🏻Guys please explain me about this

Innccurate in that in reality we know that the mass of the earth is far heavier than that of the moon.

-1 you explained the effect but not the cause by using mere analogies of marching solders and Huygens principle

@2:46 elastic, unequal masses. Difficult to tell what happens as both carts are moving. Ideally one cart is static to begin with, try with different velocities as well?

The music or its volume is so distracting.

Excellent video. I wonder, where do you get the material from? Is there a specific supplier for that, Amazon...? I teach in Mexico and most labs do not have this kind of equipment, so I'd love to create one. Thanks in advance

This is the best!

GURLIE POPS THIS IS SO GOOD I-

Can we take example trough a ruler as I thought. Is it correct? "First we will have to take a ruler on the table or any surface. With on of the finger pressing its corner gently then from the other side pushing the ruler. This will bend the ruler. So we can say the corner we pressed is the part of light wave which first entered denser medium and became slower and the other side of ruler is the part of light wave that is still in rarer medium and traveling with larger speed than the other medium. So as a result the light bent."

Mind-blowing explanation, props to the creator!!

Me: "Oh cool, a nice little informative video about boomwha--FIFTEEN YEARS AGO?!!!!" That...that is surreal. What. But no seriously, this did actually answer my question about "what the heck are these things/how do they work?" so it's a good video. :)

Friction and gravitational pull downwards will retard the ball and bring to rest.

First comment since 3 months 😅

what the hell is this comment section,why does it not match the video

Dark matter is the part of our minds/universe, we’ve yet to light up!! Galaxy 🌌 Gravity is memory!! 🐘 🐾 🥁 Inception is based on a true story!! 📺 We’re living in a dream world 🌎 😴 Planting seeds in each others minds!! 🌱 Let’s create heaven on earth!! 👼 Galaxy collisions!! 🌌 Twin flame connections!! 🔥 🔥 Superheroes!! Super pets!! Super foods!! Everything is awesome!!🤩

Best explanation I’ve heard on UA-cam

no

What a waste of time....

Wow that's awesome 😎

God bless you. Thank you for this video.

How do the MFs from the other planets affect ours?

Hard ball

Here cause my exam had a doppler ball in it, gonna go burn my jotters now

thank you

Mai thore ka dost hun ❤

This is an extremely good explanation of a very difficult concept…

But why does it stay up? Why when it spins it doesn’t get pulled down by gravity?

OMG YOU HAVE NO IDEA HOW MUCH THIS SMALL VIDEO HELPED ME! THANK YOU SO MUCH

Yes a visual representation of electron flow is extremely helpful when teaching electricity basics and I would - okay might - use this for explaining very basic electricity to Cub Scouts or young Boy/Girl Scouts, 4H, studying for their Merit Badge. This is a decent demo unit but certainly not a "great" demo device. And claiming a bottle of Air Soft BBs are "Special Beads" is, silly, misleading, and borderline shyster.

woooooooooo

too short😭😭😭😭

Great demonstration

And that is how space sounds

NOT a "great" demo. Voltage analogy is okay. Current aspect is poor. The flow of beads does depend on the difference in heights of the ends, but what about the resistance? How do you vary the "resistance" with this device? The device does NOT show the difference between a lightning bolt and a taser - the beads have the same speed because the tube ends are in the same positions. The device shows that the speed of the beads is about the same, but for a lightning strike, a better device would show MORE beads flowing! Perhaps the demo could be improved with a variable width track. Use the full width of the track for a low resistance, and only a small width for a higher resistance. Buzz did tell us that the wire is always full of electrons, but most of the tube is "empty" even when the beads are moving. BTW - this demo also reinforces the misconception that the electrons are moving quickly. The average speed of electrons, even at a 20 Amp current, is much less than a mm/s.

Needs the resistor demo. What have shown suggests a superconductor.

A great video and visual for helping students create their own mental model. It would be very fun if the spheres glowed in the dark!

Hello, I posted a question on your website. I'm not sure if it worked. But anyways I'll ask it here as well. Do you know what the uncertainty error is for this equipment? I'm trying to record the production of hydrogen for electrolysis and i'm not sure what value to use for the uncertainty. Any help would be appreciated, thanks 😊

That tree made my school life miserable
