Weird Experiment Makes Metal Grow Out of My Finger 

He’s slowly using his science smarts to become the silver surfer

Mum:”what does RU-vid even teach you go to school and pay attention!” Me:”well....Have you heard of the action lab.?”

Everyone: (Struggle to grow a single tree) This dude: (Grows metal out of his finger)

“Ok, let’s turn on the power. 3, 2, 1, --“ *AD*

Lmao he turns the electricity on and an advert for Pokemon comes on 😂

Parents: So, Who is your new Science Teacher? ME: The Action Lab

8:00 *At most it's going to heat up my finger and burn it* That's totally fine

Neighbor: *growing trees* Action lab: *growing metal trees with his finger*

Metal grows out of your finger then you are IRON MAN

*Next video: growing fingers out of metal*

This man will invent the futuristic forge which doesn't require heat

How can this video even have dislikes he just uploaded it

Absolutely Mesmerizing! You have definitely become my favorite Practical Science channel; and even when you do a more theoretical show, it's grounded and well presented with practical examples. And my middle school age kid likes your channel too! All around great stuff. Thanks for your work.

I'm an engineer at an ECU manufacturing plant. Tin dendrites is something we have to watch out for and prevent as it can cause a short in the ECU and potentially kill your vehicle. Typically we apply a liquid rubber (conformal coating) over sensitive areas of the board.

Wow! that magnified shot was incredible, well done.

Today's fact: "Bluetooth" technology was named after a 10th century king, King Harald Bluetooth. He united Denmark and Norway, just like the wireless technology united computers and cell phones.

The microscopic footage was awesome. It was so satisfying to see it forming a straight and then branched structure.

at the microscope you can see that the crystals alway growed at a right angle. why is this?

Thank you Action Lab for filling our Brains with Science

The timing on the ad was perfect

Watching Action Lab's videos makes me love Science but my teacher make me hate it.

Me:*always absent at school* Teacher: how do you answer when your absent? Me: youtube university

The solution is almost certainly stannous chloride for those wondering. It's often sold as a liquid tinning agent for processing homemade circuit boards. NurdRage showed how to make it in a video not long ago.

no one : Action lab video: How to become magneto

At first I thought you said "ten" ions and immeaditly started wondering how you counted them out lol

You're one of my favorite science RU-vidrs keep up the good work bud

Next video: "I now have adamantium claws."

This is often the reason why some electronic circuits suddenly fail, sometimes after months or years in operation. Circuits that were soldered with a tin alloy solder will sometimes develop "tin whiskers" that spontaneously grow between electrical connections and eventually result in a short circuit. This problem drives manufacturers crazy!

I feel like the way you upload videos, you'd do really well at teaching an online class. 👍

This is just a recording of when Risotto Niro first discovered his Stand

Did anyone else notice how it looked like the metallic tin made a forest at 5:03?

The nearest part of this video was seeing through the microscope. Seeing the straight lines and 90 degree angles growing was amazing.

"I've electroplated my finger". Love that. Excellent video. The microscope imagery was very interesting.

Y'all ever just like... Grow a metal tree out of your own finger

I just typed the bane of your book, and it's actually on Google! I'm gonna buy it to support you, and also to see some really cool activities!

School: teaches science Action lab: Do cool expiriments Everyone: Me: I prefer Action lab more than school

I swear I learn more from RU-vid then school could ever teach me

This is a test I perform regularly on automotive electronic parts. It's called electro-migration, it causes short circuits to happen which we don't want on circuit boards. Copper and tin are the two biggest culprits of this phenomenon.

Following the growing dendrites with the microscope is one of the absolute coolest things you have ever done on this channel, and that's really saying something

You should do the experiement first and then tell us the explanation. They way it looks a lot more fascinating, but it was still pretty cool.

lt's growing! wow! love it! Reminds when you would hold hands with your siblings and then touch the electric fence on Dad's farm!

Plot twist: he travelled to 2809 and brought a metal seed

3,2,on- Add plays Whyyyyyy

Wow that Science Exspirment was Shocking Lol !!! 😃😃

Tin does this on it’s own. The tin in solder is notorious for doing this under electrical load with just atmospheric moisture. It’s called “tin whiskers “. Toyota and NASA have been effected by this fairly recently and dramatically

This channel teaches me better and more then my college does

Careful with DC, it can cause cell damage. Awesome demonstration! This is basically a very slow variant of branching electric "discharge".

Hi action lab ! In next could you put tesla cool and van de graaf generator in stong magnetic field ? Result could be crazy

2 more experiments please: 1. This in a Vacuum Chamber 2. Let it grow 3 Dimensionally ( like in a glass or something. )

It’s so beautiful under the microscope. Like a fractal!

After all these videos you're gonna be a superhero

You should try doing it with silver as Anode and use silver nitrate for your solution, and it will make the most beautiful dendrites!

Under the microscope it looks like a crazy etch-a-sketch...

So that's how Wolverine grows his claws. The microscope view shows a fractal forming.

The tall part looks like Douglas firs if you look on the bottom it looks like the shadow of them and I've also noticed that each one of the patterns initiate the direction of 90 and 45 degree angles like a sine wave it also looks like a pulse or a heartbeat

It's 22.02 in Indonesia and u don't know why I'm watching this

So its diffusion limited aggregation?

when you're early but don't have creative ideas...

Now we need a part two of white crystals growing straight lines. Nothing circles or spirals or anything even natural forming crystals seem to grow in straight lines. I never thought about it until just now.

Music when the microscopic footage came in. Epic.

The dendrite travels up the axial tube to make a synapse, called action potential.

very cool under the microscope. you should do that more often :)

Is the liquid water?

The microscope footage was EPIC!

Maybe this will start a new trend: electroplating body parts, in stead of piercing or tattooing them.

That part where he showed the tin under the microscope, it kind of looked like the Inception.

5:35 looks just like the sound waveform!

Magnetic guy goes invisible attacks a local pick hair boy

Now I think that trees are not just a tress at all and grass is not just a grass:-)

Action lab : 3 2 1 Ad: can your hair survive damage?

1:51 “let’s turn on the power. 3.. 2.. 1..” (advertisement) 😢

If this man can make tin bonsai then we should have jet packs by now

beautiful microscopy part

This is how tree grows . So aliens do exist

*Very Impressive* but how to make torture equipments using Redstone

“Steel manufacturers hate this weird trick!”

Great, can you grow adamantium now?

I really want to see CRT TV or monitor after releasing vacuum (without damaging the picture tube of course) in vacuum chamber and after sucking air from the chamber turning that TV or monitor on whether it will still work.Then during operation try to slowly (i mean really slowly) release vacuum from chamber and see at which moment it will stop working 😉 Probably immediately after disrupting the vacuum but anyways.

Metal from ions and electrons only, no protons or neutrons required?

Microscope view was coolest part. I used to draw that same exact pattern on cocaine and am thinking maybe increase in my own electrical energy manifested same pattern into the cosmos

5:30 good intro for a movie

The fractal patterns under the microscope 😍

It grows from me too...

Everyone: *reading/typing funny comments Me: *dumbfounded by perfect 90 degree angles growing in fluid.

The part when he showed the actual footage of the reaction in the microscope reminded me of a Minecraft map generating as you walk...

I have grown infinite brain cells after watching all of his episodes

That microscope view was amazing! Why does it shoot off in 90 degree angles with the occasional 45 degree angle though?

Okay, not gonna lie, his finger has unimaginable power.

woiuld've been cool to start them off closer. Let the tin wiskers grow until they short, and melt back, and then start to grow back again.

U just keep watching when the microscope part comes 🤩

Not the trees we need, but the ones we deserve

You can make a metal spiderman web using this technology

Is it possible to have -3D is negative directions and negative dimensions?

Something awesome I noticed from Glass and various other patterns like this is that it seems the path is predetermined on moment of charge. The microscopic view looks as if they are influencing each other. But they aren't. At a point when watching it kinda all lines up to a stop. Then the influencer is coming in from the bottom or at least it's what it looks like... However you can notice that as we follow that influencer I described the previous focusing branches interlink to a point where they can't go further due to this influencer but what I find most interesting is... The paths are straight as it's the most direct route however that makes our influencer description void as it is traveling up to that point again as a direct path! So that makes the tree in its final point determined the moment you channel the current into the dish. (Not that every tree would be identical no matter the dish but in the sense that once you choose the dish and run a current 1 direction it would follow the points initially reacted with from the electricty. Like a plasma ball I guess but with where nothing can be... So that's why even if u had stupifying power you will still have shards and not powder when shattering glass. Even if the shards are as small as powder.)

It was a close up of an etch a sketch, don't believe him guys..... LOL. Joking ofc. Still think he's one of the tubers doing interesting stuff in 2021. Hard doing stuff millions haven't seen already and making it cool. Ty.

This is probably a dumb question but.... Why do they grow at the same speed regardless of how many volts you're putting into it? I would guess it has to do with how fast the electrons are moving, but I'm not entirely sure.

From the view of the microscope it looks like the newyork city 😂

Does a vacuum chamber under a near complete vacuum weigh less than one not? What makes up the space inside of a vacuum chamber when under vacuum? Just a thought that I had.

Turning on the power in 3...2..1. ▪commercial starts▪ Hahaha that wasn't what I was expecting to happen when the power got turned on in your petri dish ;)

Action lab: 3,2,1 *youtube: video will play after ad.* Me: thx youtube!😡
