Please wear protective gear lol

I bet every time his neighbours hear the "hey guys backyard scientist here" they immediately go into the bomb shelter

The chim or hum of the tin on the dry ice is due to the moment of the molecules in the dry ice. The metal is a solid and will not become any more solid then the state it's in the atoms are interlocked perfectly. The dry ice however is fluctuating between a solid and a gas (all but missing the liquid stage) this results in the atoms moving so fast under a pressure (the tin) it begins to resonate resulting in the sound. Only a few years late on this but just for those who wanted to know. This will happen with any solid material put on dry ice with pressure. We do the same thing between petri dishes in the lab I work in when we get a shipment that contains dry ice.

“It’s an ice cube!” *10 seconds later* “It’s so cold, it’s like...frozen”

Excellent experiments, and a big like for the chiming tin

dude how do you have grass

That chiming sound was the most unexpected thing I've seen in years

2:23 Now that is straight up a game sound effect right there

Fun Fact, infrared can't penetrate through glass, it acts like a mirror instead! so if your robbing a bank bring a large sheet of glass to hide from the chopper. What would you do with an infrared camera?

somehow i thought the chiming was the most interesting part..

"The remote pouring device" 😂 A string and bucket haha

I like how the camera person actually interacts instead of staying quiet

The tin chiming on the dry ice was EASILY the coolest thing I've seen in regards to metallurgy. I would never have known about it if not for this video!

Neat, a reverse leidenfrost effect.

Liquid Nitrogen: I can give frost bite to any living thing I touch. Backyard Scientist: Hold my molten aluminium.

LIZARDS!!!!!! that is one lucky little lizard. . . I ♡ LIZARDS

woah!! that chiming noise was actually really unexpected and cool! nice vid :p

That tin chime is really cool

> Pokes liquid aluminium > Doesn't hurt > Does it again > "OOOWWWW" > Suprised pikachu face

Me: How can I know he's actually smart, For all I know he cou- Me: **sees Rick and Morty shirt** Me: ahhh... A true genius

That intro was so smooth damn

Ah America. You can't buy chocolate covered toys, but you can buy dry ice at your local convenience store xD

0:16 great transition

I really appreciate the attitude of, ‘I’m not really sure why this happens, but let’s try this.’ This channel is so non-pretentious compared to other engineering/science channels on KZfaq. I really appreciate that.

am i the only one amazed by the tin when it was tinging?

The best manliest part was getting the baby lizard out with bare hands.

2:01 that’s how Minnesota is in the winter

Tbh you need a very high IQ to understand why he is wearing a Rick and Morty T-shirt.

Awww thank you for saving that baby lizard

How do you even have a lawn? It should look like someone went ham with a flamethrower.

Why have I never seen your videos before, this is amazing! I love you!

Love that crisp noise :3 soooo nice

Do you see THAT big of a difference in video quality running in "shoot time priority" so you get 4 seconds of run time?

Why is so easy to get dry ice in USA and not easy in Europe? :/

Actually when u think about it, the reaction from liquid nitrogen and molten aluminum is almost like when oil meets water. They always have to be separate, the only difference is the type of matter and how dry ice and molten aluminum has a more explosive and vigorous reaction than oil and water.

That was very satisfying to watch

Kids in Africa could have eaten that liquid nitrogen

2:20 - Best ASMR I've heard in months... That's absolutely brilliant.

4:04 *how to use tools*

That transition at the star was amazing!

2:30 The aluminum gods smile upon you.

I think metalic ponds or lakes would be cool for effect in movies or games.

2:29 when there is a nirnroot near by

“What is it hot?” “It’s cold. Damn cold!”

2:55 it's like watching the t-1000 melt

that chiming is so fucking odd ive never seen anything like it before. good on you for finding that

Woooow i love this video!!!congratulation !!!!

Can you guys please make a white noise video with the crackling tin sounds? Its sounds so beautiful 2:24

So aluminum and dry ice makes a sound like chipmunks talking to each other. Neat.

My aim when I pee 4:19

Subscribed with the notification bell!! Nice video!

This was awesome!

3:55 Poor mice

Next on BackyardScientist: Find out what happens when i drop my family in molten lava... Tune in...

Incredible stuff

This is one of the only “science experiment” channels that actually does science experiments and doesn’t just destroy iPhones. You have earned yourself a like and a subscriber.

I just realized that he sounds like kermit the frog

Still not hotter than my mixtape

love your shirt I watched your video's for awhile but imma subscribe now

That is a great transition

Oh, how the entropy increases in the universe!

"Oh, look at that. It's like a... OW! Yup, I deserve that." XD XD

I love the tins resonance chime 💕

Yo the tin making that noise! Unreal :)

Aw, that was nice of you to protect that little lizard.....points with God!

I love the way liquid metal looks

I love these experiments Damn!!!!!

some cool moments, overall not as exciting as expected, but thumbs up for trying it.

could you upload that sound at 2:25 for me to use without you talking ? i'm in love with it !!!

You are the best you went out of your way just to save a cute little lizard

“Oh look at that it’s like uh-OWW!” 😂💀

That transition at the beginning is under appreciated

Next time Molten Salt Vs Liquid Nitrogen. :)

The chiming is so cool. And soothing!

2:24 - that sounded pretty neat. Almost sounds like it was a sound that was added into the video. Wish I knew what made it sound like that.

bloody hell, mate. 6 weeks of cleaning up xD nice video

Ah, this is a fun one I just recently explored. The reason the molten Aluminum slides off of the surface of the ice is due to what is called the Leidenfrost Effect. Effectively, the dry ice is creating a buffer of gas between it's solid state and the liquid Aluminum, allowing the metal to float right off of it. And it also explains the volcano effect, where the gas is pushing its way through the molten metal. You can see the same effect if you heat up a pot and drop water droplets into it. The reason they don't instantly vaporize, is due to this same effect. You can actually see the same effect when he pours the liquid nitrogen onto the molten aluminum, how the liquid nitrogen floats around on the surface. Pretty neat stuff.

you are downright reckless with your safety in this video... honestly, i couldn't care less if you end up severely injuring yourself, but please try and set a good example for others by treating liquid nitrogen with the respect it deserves.

After watching the first pour, I'm assuming the Leidenfrost effect makes the dry ice not really melt much. Although, I don't know if that's correct, because with Leidenfrost, it's usually a cool liquid introduced to a hot surface (water into a hot frypan, for example), whereas it's the opposite in this experiment. However, I believe the effect produced is likely the same; a layer of vapor between the hot liquid and the cold material that prevents direct contact. Does a reverse Leidenfrost effect have a proper name?

All this and I’m still thinking about that cute little lizard at the beginning 😍

Love your videos! One of my favorite channels, please don't stop making videos!

someone needs to create the "liquid nirtogen bucket challenge"

I learn a lot from this so thAnks..

When molten Antimony cools, the same cool pinging noises occur due to the crystals cooling and breaking and bouncing around. You should check out that phenomenon!

4:07 sounds like you're murdering squeaky toys

I like how within 18 seconds of your video, you decide to look at the camera while spilling liquid nitrogen into the dry ice...You're either lucky it didn't spill all over your hand, or really good at holding a scream in.

John Connor: So this other guy: he's a Terminator like you, right? The Terminator: Not like me. A T-1000, advanced prototype. John Connor: You mean more advanced than you are? The Terminator: Yes. A mimetic polyalloy. John Connor: What the hell does that mean? The Terminator: Molten Aluminum.

the tin sound is just beautiful

Can you make a freeze ray? Similar to your flamethrower?

"It started making a chiming sound" I CHIME IN WITH A HAVENT YOU PEOPLE EVER HEARD OF

One of your coolest intros😂

Love the shirt at the very beginning of the video

I'm so glad you noticed the lizard. Would've been sad to find it cooked. (But maybe delicious, who knows)

3:52 "Try not to cringe challenge"

Oh man! I always wondered what happens when you spill molten aluminium onto dry ice, thanks!

Excellent demo guys, not as spectacular as the molten salt in water. And demonstrates the exact opposite reaction, because as you say, they could not mix fast enough to get dramatic. And using carbon dioxide to make foamy aluminum is routine product, really kool stuff...

You've done how many experiments like this, yet you're still surprised by the Leidenfrost effect?

Shit I didn't know Kermit the frog made KZfaq videos

Really cool introduction

That noise i know omg its so magical!!
