How

Who the hell gives dislike to this channel's videos

0:43 the pencil

Magic, huhu

1.36 action lab says the F bomb?

20$

1:48 he’s doing dab

That the keys do not fall to the ground

I will bed $100

i won

Well if u hold it vertically does it do the same

OK everybody today I'm going to....

Dude you gotta watch this!! One guy even risked his life trusting the science behind this same principle.. http://youtu.be/eR6tzU5w3EM This is from a popular Tamil language scientific channel from India!! He makes videos explaining the science behind everything practically.. It is so useful for the students here.. You may not understand the language but see his concept and commitment.. His videos are very popular among Tamil people from India..

i like your vids before watching because you always create awesome videos!!❤️❤️

I love your videos and I have a request can u explain why light doesn’t have mass.. I think photon should have mass because since the Newton’s law and Einstein’s formula both shows that light have mass_> Newton’s law:- to move something massive you need to have enough amount of mass and velocity. Einstein’s formula_> E=mc^2 which means energy is mass times speed of light^2 and then the confusion comes some says for the photon it E=pc^2 which means Energy is momentum times speed of light^2 but momentum also comes from mass and velocity, and if light doesn’t have mass how can it have energy, if it because of the wave and frequency what proves that there is no mass. I really want to know the answer please help me if you can.

Wow!!!!!!

do this on a bigger scale please

LAME

Wow flying keys wtf

He looks so small compared to the door

Elementary

Huh look at that. Huh look at that guys. Huh

Would the same thing happen if you put a feather as the lighter object? The affect of gravity on the feather is reduced due to the air density acting on the feather slowing the feathers fall. So I don't think the feather would fall far enough for the string to hook the pencil and I suspect the keys or vase in this case would just hit the ground first.

HuH he still fliying HUH HUUUUUUUUUUUOH

neither will

Hah.

1:39 As all things should be

I watch 480p

0:54 keys

It’s wrapping around it

IM 8 YEAR OLD AND IM NOT GIVING YOU 20$ DOLLARS!!!!

Thats not mysterious physics. Its just *basic knowledge*

1:53 Minecraft Villager_Sound.mp3

Is there a minimum length required for the string? I imagine there must be.

+Jeff O I see. But how about too short, but still long enough to wrap around the pencil at least one time.

Definitely. Too long a string, and his wife's glass vase crashes to the ground.

And you need a friend that doesn't understand physics. 😁

excuse me, did you say your 'wife' is going to be upset?

+H L I don't understand the beard comment, but he showed his wife in a previous video.

+Jeff O Obviously he doesn't have a wife, he has a beard

Only if the experiment failed and the glass vase crashed to the ground.

(at the bar) watch as I attach this baby to the matchbox and line, you're about to owe me $20 sir bwahaha

Anyone who’s ever seen Batman from the 90’s seen this coming. #batterang

It did what I thought it would do. Never had one lesson :)

In this setup the keys will fall first because the lenght of the cord from the matchbox to the pen is too short. I guess I have to try it out now damned, I have to time for this!

What I was thinking. What will happen if you change the angle of the matchbox from 90° to 45°? I guess it will lengthen the drop distance by more than 2x, i'd say 3x.

Thanks you bro.

pft, on TV they do it with humans

Can a propeller work in vacuum

Try to freeze the phone and try to call it

I saw it coming heh the positioning was pretty obvious. Didn't know it got exponential with every turn that's very interesting but makes sense!

But the keys are *falling*!

This is kid trick If I bet money my every friends will win everytime

Is there any way to play with light and make a life size object invisible?

+Jeff O yes it does seem a lot of stuff to be kept aside so no doubt there's still debate going on about this topic even after so many decades.... And personally talking, I do believe that the US government and military has something more than what it shows to the world.

+Dark Star Yes, but it was all those things - light, space, and time. Some people think it never even happened, although there's a lot of evidence that "something" happened. Whether or not a ship was rendered optically invisible is up for debate. Tesla's technology at the time was supposedly used for the experiment. And the fact that some sailors on the ship traveled through time just adds to the allure. It's a pretty big topic to get into, but Google obviously has no shortage of information about it. There was even a film made about it, and there's probably many documentaries about it on YouTube.

+Jeff O ok so I've been through the Philadelphia experiment thing and I can say what I asked was "to play with light" not to play with the space and time... Dude trust me if that Philadelphia experiment was real then it was crazy scary

+Jeff O really? I've gotta check it out then

They did that during the Philadelphia Experiment..... supposedly, anyway.

hack smith build a driveile snow plow and sell it like make a business out of it to do more projects

Enjoyed the genuine laugh of relief when it worked with the vase! Great vid, dude

Level 1 crook,takes 20 bucks. Level 100 boss

pls put ads. you need money

Now redo this with a vice!

Do a collab with The King of Random.

I thought it was cool that the match box stopped the keys from falling before it even completed its first revolution around the pencil.

Please try this and see if it works, you're the only youtuber that I think will actually do it without faking anything! http://www.youtube.com/watch?v=18RyMadIE_Q Like so he can see!

+juan garcia Oof, time to dig deep into his channel..

He already did that 9 months ago.

My friends would kill me if I Bet This

I have an experiment for you. How does large debris emptying the oceans upon the earth causing the great flood create a chaotic recurring & overlapping atmospheric blueprint in its mass/volume displacement ?? SEE amature forensic video (Human Intervention 2018) on you tube thx

You should put subtitles in every languages.

Awesome! BTW...where did you get your Fibonacci shirt?

Can metal rust in a vacuum?

Nope. Rust requires oxygen.

This seemed rather obvious, even when you know nothing of physics.

He owns a Nissan Altima?!?! I have those specific keys too! 0:20

*holy cow*

It forms a fibonacci spiral. Its already in lmes tamil channel

What is cold welding how does it work in space

put a juul in your vacuum chamber and see if it smokes

As long as that first loop works without hitting the string and bouncing back, golden,,,if not, yikes.

I owe you $20

Hi, Action Lab, I want you to try the experiment, what will happen if we start creating a vacuum when there is an electric arc between two wire.

_Will it match box?_ {WOT?} {No but a tin can} {Yes but it wont fall} {idk}

This is very cool. I love all your experiments...

why don't you create a video on creating sugar charcoal ?

The video starts at 0:00 , you're welcome

Yo! Can you please explain the physics behind formation of shadows?

+Firebolt73 It's not black. It's only a darker shade of color than the part that isn't in shadow. The darker something is, the more it can look black, but it's only emanating less light from the colors that it's giving off. For example, if you turn down the brightness on your monitor to a very low level, it's dark, but it's not black. It would only be black when you completely turn off the monitor.

+Jeff O yeah but why is it only black colored

The formation of shadows occur when an object blocks a light source from reaching it's destination, such as a wall.

1. No, of course I don't take the bet. Even if I was sure I was right (and if so I should wonder why you're proposing the bet), *you don't offer anything in exchange*. I wouldn't take a bet where I pay $20 if there's no sunrise tomorrow, even counting "sunrise" including "behind clouds" and stuff, if you didn't offer anything in return if there was. 2. When you first proposed the bet you were holding the matchbox well below the pencil, not out horizontally. I expect it wouldn't work as well if you actually released it from there.

You should start your own show..."physics magic"

Who remembers his lopy voice before he speaks

2:27 thumb nail

i heard there's a "magic trick" where a very strong man can't pick up a 110lb woman. The trick is for the woman to pull one of her legs back a step, and that's it. Can you explain how this works????

You said FRIST right? So I win

This isn't magic it's friction

I wanna see this on a massive scale with a larger ratio!!

Prof. Walter Lewis also says this phrase "PHYSICS WORKS".....

i know a magic trick too: if you throw a ball up in the air it will magically come back

Here’s 20 dollars dollarsdollarsdollarsdollarsdollars dollarsdollarsdollarsdollarsdollarsdollarsdollarsdollarsdollarsdollars dollarsdollarsdollarsdollarsdollars

Very cool video.

Neither will hit the ground

*Amazing* 👍👍👍👍👍

105 people owes you 20 dollars

Omg i was so nervous for you lol

You owe me $20, I knew exactly what would happen, Indiana Jones Style!

This dude took my $20.

What......really, are there people who can't predict what would happen.. or at least understand without the explanation?

Nice trick !

That's a neat trick. It appears to be a combination of pendulum motion and angular momentum. VERY cool. 👍

Someone should tie them selves to something and try this

Cool

This reminded me of something I've observed and thought of since I was a kid. Get a Philips screwdriver, a medium to large ring that will fit over the tip of the screwdriver but not the handle. Some string that won't break if spun and some type of weight like a toy car. Cut the string to about a foot. Tie one end of the string to the car and the other to the ring. Slip the ring over the tip of the screwdriver so it rests on the handle. Grab the tip of the screwdriver and spin the string and the toy car. The handle should keep the ring from flying off. Notice how little effort it takes to spin the car. Try to make tight small movements but keep it spinning. Be careful not to hit yourself. Now if the car was a magnet and you spun this inside a large coil of wire, would a current be induced? If you video recorded your hand movements (which I suspect requires more effort than it actually seems) you could build a robot cog or gear that could simulate the movement of your hand and control it with a small motor. Now I know from physics that you can never generate more power than you use, but it sure seems like in this scenario it is a lot of gain for a little effort. I have wanted to ask a science teacher this since I was a kid but always forgot. Thank you for reminding me. If you could explain to me why it seems like this is taking very little effort to spin this so fast and why we could not use this in some way to make electricity? Thank you. Sorry for being so long winded.

It takes so little effort because you are adding the energy in small amounts at a time, so you just don't notice it. You are correct that you will not get more energy out than you put in. You just have a system with little friction so once you get it moving you don't have to add a lot to keep it moving. If you added a coil of wire and the car were a magnet you would see the car very quickly come to a stop. Once you added the coil you'd have to put some real work in to move it and keep it moving.

Can you share a link to the paper? Thanks!
