A little correction at 6:50 Carbon dioxide is a colourless gas. The white vapour is water that condenses when exposed to the cold CO2 That said, this was an excellent video and that looks like a fun experiment to try if I find an extra block of dry ice lying around the lab.

[@scowell]

CO2 is not a white gas! The cold clear gas has condensed water vapor in it. Sorry, I'm a pedant.

[@Varksterable]

scowell Being accurate in science isn't pedantry. It's just doing science. (Sorry to be a pedant. ;))

[@acepilot1]

He was merely pointing out that the gas was frothy and white, he didn’t say CO2 gas is frothy and white, the fact that water frozen makes it white should be a given

[@chrisjvas]

@@acepilot1thought I should add more pedantry to this thread after all these years as I feel what you said wasn’t quite correct. Ice is most definitely not white, all of the time. That just happens when air bubbles are trapped within, thus increasing the opacity. NileRed made a video that somewhat explains this

[@lbaxel9122]

@@chrisjvasyeah and the bubbles make it so the light that travels to your eyes is white. Color is relative.

[@malayrojak]

Man that reaction of magnesium inside the dry ice is awesome. I would not have expected it to "steal" the oxygen from the CO2 to form elemental carbon. Reminds me of the reaction between Nitric acid and copper in High school. Wasn't expecting anything to happen, but boy was I wrong.

[@electronicballast]

"we're gonna have to wait until it's cool" The strangest thing to hear when talking about dry ice.

[@mannymnts]

Your videos are so amazing, greattings from Ecuador.

[@ShinyStuffingMix]

i have a question.. if you had a block of dry ice, a decently insulated beverage cooler, and a piece of camping thermal material.. if you loosely wrapped the dry ice block in the thermal material and placed that inside the cooler then closed the lid.. granted you had a tiny hole drilled into the bottom of the cooler, granted the lid of the cooler wasn't locked shut for precaution, roughly how long would that drill hole slowly shoot out co2 gas?

[@berserkberserk997]

the problem is also that we are cutting down large amounts of plants in general.

[@assasinman98]

hey for the experiment with the CO2 and magnesium does it have to be magnesium or could i use a substitute?

[@ShinyStuffingMix]

also, sorry, would there be any chance that the "evaporating, melting?" dry ice would have any chemical reactions with the thermal material? would it give off any toxins? i've seen a sewn together mylar/fabric sheet i'm going to cut up and use. maybe ill punch one or two holes in the thermal fabric ..

[@1959Edsel]

You can also use a relatively large chunk of dry ice as a sort of air hockey puck. Instead of gas coming up from under the table, you have gas coming down from under the puck. This works best on a smooth floor (linoleum or cement).

[@AdventLt]

Hello i have a sparkling lighter, made of Mg, and when you hit with steel it causes sparks, but im wondering if i would heat my Mg stick would it light up?

[@SupportShotgun]

That dry ice chamber is awesome!

[@P00P0STER0US]

That's a neat reaction. I love playing with dry ice :o) In our lab, I used to put some in the toilet.

[@artstsym]

Is enough solid C02 capable of actually freezing some of the water, or would the reaction cause too much motion to allow that?

[@rfldss89]

how long does the reaction last ?

[@kurtstory9466]

Is dry ice this difficult to find that you have to order it, rather than pick it up in a local shop? A friend in the UK has found getting some for a cloud chamber nearly impossible.

[@EzyoMusic]

One of the science teachers at the high school I graduated from liked to put dry ice in film containers and set them in the rooms of unsuspecting teachers. It was hilarious to see their reactions.

[@pleappleappleap]

Do the alkali metals react with solid CO2?

[@Seeds-Of-The-Wayside]

5:45 He misspeaks here. The White Cloud you are viewing is not the carbon dioxide gas collected, it is the water vapor in the air freezing as it cools in the carbon dioxide which is evaporating, and is also colorless.

[@seshachary5580]

great educational videos thank you regards

[@boy887766]

I just adore the mug in this video saying Rocket Scientist....next to the professor !

[@grndmstrjoe]

In my opinion, this video should be revisited. A suggestion to do this is to put an indicator in water before dropping the dry ice in it to show that when CO2 goes in water, carbonic acid forms. Carbonic acid is a hot topic in the whole 'global warming' debate since increasing levels of CO2 increases the amount of carbonic acid in our water systems which affects marine life.

[@fastphys]

is dry ice clear like water ice? It looks white at first but it looked clear when put in water.

[@blue4splash]

@oOoxelAoOo well I'll give you another interesting question :D why in the wineter when we breath you are "steamy" because of the water from the air you expire?

Great series. Cool - First part was captioned in English, please caption part two in English as well. Jim

[@caffeinepizza]

Engine idea (will it work?) 1. Water is put in to electrolysis. 2. Both the Hydrogen and Oxygen are transported in to combustion chamber. 3. Spark makes fire. Reaction makes water. 4. Water goes back to the tank and goes through electrolysis again. 5. Repeat Steps 1 - 4. 6. ??? 7. PROFIT !!

[@gatin9015]

Has the pressure reaction of CO2 been considered to be used like the steam systems at any time??

[@CoolMinty]

[@brainiac777]

awesome, we did this on the last day of school, on a slightly smaller scale.

[@Bimm3rcc]

Could be nice addition to add the reactions you show as text on the video! :)

[@callumWLB]

adding on to what he said, the fact the the compound CO2 is different to the elemental carbon means that it interacts with light differently, giving it a different colour

[@G2DP]

[@Bourinos02]

"Bullseye!" Epic moment :D

[@bikingnutcase0]

I tried to extinguish an Aluminium/Magnesium alloy swarf fire with a CO2 fire extinguisher once. It was in the bed of a lathe where there may also have been some water and oil present too. It was somewhat energetic! Massive fireball. Grey powder everywhere afterwards, I assume this would be the Aluminium and Magnesium oxide and carbon they mention.

[@hugobitard7882]

Another awsome chemical reaction that i love is thermite with dry ice or CO2 in a solid phase. It gives an enormous explosion with simple iron "bubbles" forming... That reaction is yet unexplicated...

[@jq747]

LOL watching that first bit made me think, "Chuck Norris cuts CO2 with a saw" =D

[@sporkafife]

That one with the coin sounded like the CO2 was screeching! That's pretty cool.

[@Dazzwidd]

You like to torture CO2 do you? 😅

[@CorginShep]

@Serostern A lot of the magnesium rods that you get from shops are mixed with other metals. Also the fact that it's a fat*more so* rod makes it harder to ignite. You can shave it into filings/fine particles and ignite it that way. ;)

[@rolfen]

Isn't fun to destroy your lab?

[@safibn1]

How much is dry ice? And magnesium? I think I've found a replacement for all of my video games and internet. Very nice experiments, nice video. I really enjoyed seeing the elemental carbon be created from CO2. I like the white -> black transition..

[@Murtage33e]

you can probably buy some at your local supermarket, i know my local publix sells it.

[@lucazsy]

At 0:16 we can see the most effective way to cut CO2 emissions!

[@tailr]

awsome!!

[@Chlorate299]

I was referring to the gas expanding from the fire extinguisher. That is a process where the pressure is changing from high to low with virtually no energy transfer to the working fluid, so temperature does indeed drop allowing for the formation of solid carbon dioxide. It does not hold true for the solid carbon dioxide boiling, since as you rightly stated, heat is being transferred to the fluid. Therefore the CO2 gas cannot and does not get cold enough to condense back into a solid. q.e.d

[@Willam_J]

Every Periodic Video - "Let's set it on fire!" :-D

[@sharperguy]

As far as I've heard, most scientists agree that even with the increasing levels of carbon dioxide being released by humans, the direct effect could only cause about half a degree or warming over the next 100 years. The reason there is a panic is because many people think that this initial warming may be multiplied by various environmental factors such as increased water vapour. This multiplier effect is really what scientists argue about and is not so clear cut as many think.

[@Adrenalinism]

just a bit confused... when the magnesium started reacting to form the oxide, why did it nick oxygen atoms from the carbon dioxide? why did it just not react?

[@assasinman98]

thanks for that :)

[@DesViper]

7:00, where can i get a lab coat like that?

[@pleappleappleap]

I wonder what would happen dropping magnesium (or sodium? caesium?) into LOX.

[@kattejuice]

@blue4splash very true! thats also why butane gas is cold when it comes out of a can, like lighter refill. the gas will take energy/heat from anything around it. liquid butane will take the heat i the air, makeing it cold -since the air has no heat anymore. at the same time the liquid becomes a gas since it got the energy/heat it needed. right? PS: im 15, but i still find this pretty simple.

[@samalbury9183]

Am I the only one that shivers when Neil is sawing

[@rockyman777]

A small correction to the dense white cloud you see above the water which is infact: tiny water crystals cooled down from the surrounding air. Carbon dioxide is and will always be colorless and invisible in it's gaseous form.

[@fractalnomics]

By the way Venus 2:11 has a pressure of 90 bar compared to Earth's 1bar (some 3 to 4 times the pressure of an average diesel engine compression). Physics!

[@LiiMuRi]

Cool. I have to ask if our workshop will build me a cannon too.

[@Withnail1969]

@tubaboy71 what is 90+? i work in centigrade.

[@jdbg1]

Dry ice sounded weird. But now that its on fire i just think you're fucking with me...

[@drokles]

Hehe, it's funny how the topic global warming is unavoidable as soon as the chemical CO2 is mentioned. Good job guys, this was a treat :D.

[@chris24hdez]

I LOVE this idea for converting harmful carbon dioxide into a harmless solid, black carbon.

[@gorillaau]

The energy required to make the magnesium makes this method bad for removing CO2 from the atmosphere.

[@lifeforce3451]

Magnesium is not cheap

[@the1thatgotirwin]

dry ice is very useful when it comes to painting a house

[@codediporpal]

At first I wondered why they were not wearing safety glasses, and then I noticed they're wearing fashionable prescription safety glasses.

[@jhyland87]

Can you use CO2 as uce cubes instead of regular ice? They wouldnt dilute the drink and would cool it down quicker maybe

[@0Sebek0]

Yes, I believe the sea is like a huge soda can with a lot of CO2 dissolved in it, so as the temperature would rise slowly with the gas we produce, the seas release that gas multiplying the effects and I don't really know how much. It's maybe like a certain activation energy for a destructive enviormental process, that we may be reaching. About the dry ice in the bottle, was it sealed or just in contact with the surface of the table? because then how did the pressure raised without lifting it?

[@jeffreysokal7264]

You guys/ gals are great but I'm humorously glad there aren't more disasters.

[@nickcorn93]

@DrD0000M I did a quick calculation and it turns out you would have to invest around 1500 kJ - 1600 kJ at the MINIMUM to make 2 mol (recycled, following your method) of Mg metal (and far more if you extract it from nature, over 2000 kJ). Since the reaction is 2 Mg + CO2 -> 2MgO + C, you can process only 1 mol of CO2 this way. If we look at the combustion of octane, C8H8+6O2->8CO2+4H2O you produce 8 mol of CO2 and get 5070 kJ out per mol. But you would need 12000 kJ to get rid of the CO2!
