The Sci Guys: Science at Home - SE2 - EP2: Air Pressure Can Crush - Can Implosions 

my science teacher really has good taste in RU-vid videos ngl. quarantine school work.

yall dont understand the pain i went through typing this science hw link in manually

This is made incredibly relevant by the recent news

This video is going to get a lot of views today

Without this video I wouldnt be able to finish my chemistry assignment. You guys teach way better than my science teacher lol

There's a key step that is not explained here, which is that after heating the can on the stove, the can is turned upside down and EMPTIED OF HOT WATER. This gives some of the hot air (water vapour) inside the can a chance to escape, which means the pressure inside the can equals the pressure outside the can before it's put in the water. This is important! When the can is put in the water, the opening of the can is covered by the water and a VACUUM is created. This vacuum means that when the water vapour inside the can cools and shrinks, the pressure inside the can is suddenly weaker than the pressure outside the can, and that's why the can is crushed. If the air pressure inside the can is greater than the air pressure outside the can when the can is placed in the water, then cooling the water vapour inside the can would result in merely making the air pressure inside the can the same as the air pressure outside the can, and no crushing would occur.

The titanic thing made me think of this!

Thanks so much! I had a lab report due on this, and you helped me to understand it. Got an A+!

Who is here after the whole submarine thing?

Thanks so much for this video! I understood everything and made my notes myself from your guys' explanation, because the notes on my teachers ppt were so confusing! The practical experiment helped as well, thanks again! This was a big help :)

Teacher: watch this link. Me: looking though the comments

omg this is an amazing explanation!! Thanks all for the support!!!

The banter in this video is just out of this world

Billionaire smoothie

You guys are awesome your videos help me be more creative . Love ya both I keep up the good work. Happy new year by the way

So this happened - titanic sub drama

So this is what happened to that submarine

Slap a motor on it, weld it shut, add a joystick, and charge rich Lego people to explore the Lego titanic.

These guys with their gloves, eye protection and apron took safety more seriously than the guy in charge of the Titan submersible. May they all rest in peace.

Take a large body of water and a leaky submersible .....

You guys are waay better than my chem teacher

This is the end results of Titanic sub exploration

Helping me with my chemistry Performance Task, Thank you guys

It helped me with my science project Thank you

This is about to get very popular because of the recent submarine incident :(

Thanks for helping me explain my science lab!

POV: You're a fish watching a bunch of scummy billionaires about to bite the big one

Thank you so so much for explaining this in a good manner

such a good episode guys!

Thanks for the inspiration!

titan sub brought me here

who's hear after the Titan Submarine implosion?

Very nice explanation.

Thank you guys... I was trying to understand this from 1 hour... And you guys made me understood it easily ... Thank you so much

Just trying to figure out how that submarine imploded…

Thanks! I missed the day we did this lab and your video helped me make it up and understand it

This helped me with my homework sooooo much thx 😂

"ryan gotta crush cans" "yeah you did" me and my friends be like~

Just watched a video talking about why the pipes of the Titanic collapsed, and guy was saying it was exactly this concept but on a much larger scale. The superheated thin metal cylinders touched the freezing arctic waters and snapped the support wires due to air pressure, before finally toppling over into the ocean. Maybe that was one of the many loud metallic booms they described hearing, the pressure reaction.

Thanks so much you helped me finish my science project

ty for helping me for my science homework

Thank you !!!! I just understood this topic .

i very much enjoyed this thanks for doing my chem homework : )

i was literally about to give up and get a F but after seeing that this is so easy to make and explain i might get a good grade thanks!

Nicely done

Sick vid bro!

love it!!!!!

Thanks for you guys cause my experiment is related to this and it helped

I watched my science teacher, Ms. Perry do this in science class today!

God bless you two guys So beautifully explained We enjoyed watching it Very informative Superb animation Sending lots of love blessings and wishes to you two👌👌🙏🏻🙏🏻

what happened to the titan submersible multiplied by oh, lets say, 100 fold

You guys helped me on my home work and your so good you got a sub

Is there any alternative for empty can? the video is amazing!

thank you I’ll use this for my lab on Friday

This is very useful thank u

helped me with my homework

So cool

nice experiment

This helped me with homework on why divers have/ need watches when they go lower than 50m as well as i did this experiment twice except once it steamed we put plastercine over and one exploded because of the pressure the other actually did what it was supposed to.

Wow I wasn't expecting my science teacher to tell me to watch something cool

"Today we're going to be using basic, everyday equipment, so we're gonna need multiple pieces of chemistry lab protection to make sure our eyes, bodies, and hands are safe from the dangers of simple cooking methods."

I enjoyed it

Thanks helped me with my homework

We watched this in my science lesson!

Who else is here because of the Titan submarine?

Guys thank you so much for video because its informative for the scholars

Thank you

✋Here due to recent events

Thanks really helped me in homework

I think a few of us can say that we are here because of the now imploded submersible, the Titan, which was supposed to carry 5 people down to the Titanic wreckage. May they rest in peace.

Well Atleast Someone Is Benefiting From The Titanics Sub Disaster 😂 Enjoy The Views On You’re Videos Guy Jaja

Love it

Hello I just saw this in my 5th period science class!

thx so much i have to do a science experiment and u helped me

This video helped me understand what to do cause I was confused about what to do.

Very good video for science lol

Your videos have compelled me to comment.Really you guys are awesome. And Can you please make a video about electrochemical cell because it is included in IGCSE and i find it difficult compared to other chemistry Topics.

why is my science teacher making me watch this?

The titanic submarine implosion😮

Hey sci guys you have explained it very well Thanks loved the video

that was so cool

Very good explanation in my book it is written in very hard words and then I find your videos you helped me a lot but I have a doubts can we do it without googles 🙏

Nice Video

I did this in science class. It was cool

Thanks for the homework

I tried but i failed again and again

This video helps me do my homework and my class did the same experiment I like your video I also like the way you explain it with pictures that real helped me understand how you did it.😃😄😜😃😉

THANKS SO MUCH!!!!!!!!

wow very cool

Really epic

interesting video

So much fun

Looks like I wasn’t the only one that their science teacher assigned this assignment

thanks

Can u do an experiment using entropy as a source of power? Like make the can a cylinder draw a piston up and turn a crankshaft and try to slow it down by producing energy. Seems like we are doing it backwards. A million ways to use entropy as an energy source.

Used to do this with a b tank and a small tip in plumbing class. Cans have changed. Used to get them perfectly flat

nice.

awesome

We learned this in class lol😂😂

Nice
