Vaporize some vegetable glycerin mixed with that you get a super fog that stays longer just a few inches off the ground.. fog juice & dry ice mixture is movie quality..
@@fsommer1 He would never own a Prius. Anyone who is intelligent like he is knows that hybrid and electric cars are by far worse on humanity than any gas burning vehicle. All the toxic chemicals that are just in a lithium ion battery, and the slaves that have to mine the toxic material. It's the worst.
@@victorcercasin A while ago the son made a video on the channel and said that he was the son of the main presenter and people thought it was funny. When the main presenter returned he said he was the father of the son of the main presenter.
@@TechIngredients Will you be answering comment questions in the next video? I posted a question related to the temperatures of the plasma you were creating.
@@meandnoother the temperature in these extreme environments is kind of strange. You can easily reach millions of degrees in such a plasma tube, but since there is not a lot of pressure, and therefore not many particles, they can't really transfer the heat effectively. Also, despite the high temperature, the thermal energy in such a low pressure plasma is not that high, because, again, there are not many particles that have this temperature.
Fun physiology fact, breathing slightly elevated CO2 concentrations can trigger panic attacks in susceptible individuals and is used for research into anxiety treatments.
You are more likely to pass out from too much CO2 than to little O2. CO2 ist toxic in higher concentrations. Also, if you are breathing in lots of CO2 you will definitely notice because it creates the acid H2CO3 when it comes into contact with water. It really stings in your nose. You usually don't notice it when it is in lower, but still dangerous concentrations, but dry ice is pure CO2 and if you don't mix the air really well, it will sink to the floor of the room and the upper layer of air (in which your head is located when standing) will stay relatively save to breathe. Therefore if you do end up inhaling the fog, you can definitely feel it, because it has lots of CO2 in it.
Some of these fun projects remind me of the early King of Random stuff back when Grant Thompson (RIP) was putting out amazing projects like building a microwave-transistor welder and his TV-lens solar heater. I am glad you are taking on fun projects as well, but please don't stop with the highly technical videos!
I’m lucky enough to have and endless supply of dry ice:) We use it for abrasive blasting where I work! Much better than sand blasting, no clean up and we have a lot of fun if there is extra at the end of a job!
Did you know that they clean the largest telescope mirrors in the world with dry ice snow. A little less forceful, but basically the same. The CO2 gas levitates the abrasive dust and debris away without scratching the surface.
I like this idea. I built a mineral-oil based hazer using an onboard compressor and several vacuum generators. It passes air through the generators, each using a venturi effect sucking up the oil into the air stream, cracking the oil and sending it out through some small marble filter to keep the particle size tiny. Basically a homemade version of commercial units, for a fraction of the cost. I think your design and mine could make some really cool concert lighting effects - mine for lighting and increasing depth and yours for floor effects.
@@TechIngredients I've played with dry ice in the past and always liked that slight tingle when one inhales a bit of it. I would just be worried about the CO2 displacing enough oxygen to be an asphyxiation hazard, or does the CO2 fog entrain sufficient Oxygen in the flow ??
@@TechIngredients Piss poor reply. I watch all your videos but you have made a big mistake on this one. People have died from dry ice! PS have you been drinking too much of that Moonshine??
@@andyb6120 don't be rude. A warning would have been appropriate, but as long as you don't intentionally do this in a small closed room, with a shit ton of Fans to mix the air and raise the CO2 concentrations in upper layers you are relatively save. The fog as it comes out of the machine is almost unbreathable. It really stings. It's only a problem if the overall concentration throughout the whole room are low enough, so that you can't detect it anymore, but dangerous enough to cause harm.
Thanks, fun video. You know what would be great? A Tech Ingredients web page where viewers can see the current status of every project and upvote projects they'd like to see more of. For example, I've been wondering if we're going to see anymore on magnetohydrodynamics and magnetics generally.... thanks for considering!
This looks fun, looking forward to the full video. And as always - it's quite possible to have fun without dying, if you think about what you're doing :)
@@UltraBadass In Nyiragongo and Nyamulagira in Africa there depressions in the ground that animals climb in to and never climb out of again. The depressions are full of Co2 and it starves the animals of oxygen in the blood so there muscles can't get them out. I have been doing special effects for film and TV for more than 20 years and we would never pump the output of dry ice towards actors or crew. In fact just a few weeks ago we had to flood fog over actors in a pit as if they were being gassed. They would have been killed by dry ice vapour. Each take was longer than 2 minute while they appeared to struggle to escape the gas. We use dry ice to "cool" regular smoke machine output so it sits low and simulates this.
I work with Carbon DIoxide and dry ice for a living. The little bit that he had wasn't enough to cause asphyxiation. In a small area, like a closet, it may cause problems, but in the areas he's working in it easily spreads out or he had ventilation.
Cool! Added bonus you don't have to deal with any propylene glycol or vegetable glycerin like normal machines. Not to mention the slight fire hazard of the heating elements in those smoke machines.
Great videos especially the serious ones. I don't comment too often bc i ve little time to spare really. You realize my dream of having a home lab to put these various kinds of experiments and at some cases even create better solutions than commercial ones or create something totally novel. Thank you very much for sharing.
Careful with those Subarus. Scottie says they blow head gaskets a lot, especially the 6 cylinder. I'm the guy that said I'd spend the pandemic in a pub. Or something like that. But the pubs are closed. Doing fine in our bunker here. Cheers. Great video. I may build something like this.
Very cool. I’d also love to see you make the foggers that rely on heating elements and a mixed liquid. High end models are extremely expensive but it seems like you could give folks a better understanding of how they work and how to make their own. Love the channel!
Sure, it's not really complicated mechanically. We have a few and the mid level glycerin based machines are not too expensive. From my experience as a laser DJ, I think multiple smaller machines give a better dispersion especially with DMX or other control and sometimes a simple box fan coupled with a fogger helps.
I've only seen the first 30 seconds so far, but it reminded me of a funny story. To summarize... when we were younger, one of my buddies bought a fog machine as a wedding gift for some mutual friends to use on their honeymoon. LOLOLOL
@@person800 Tell that to the people who have died in similar circumstances. Not everyone knows CO2 is heavier than air, nor that dry ice produces substantial volumes of the gas.
re: "Tell that to the people who have died in similar circumstances. " Why WE LOST a few hundred thousand to CO2 intoxication JUST the last few months ... no - wait! That was Covid-19 ...
Unless you are a firefighter wearing a SCBA And wanting to give realistic view without the carcinogens. We have always burned straw to fill up rooms with smoke and then our bunker gear and clothing stinks.
That's very useful comment. Famous case of death from dry ice happend this winter in Russia. Group of people died in sauna playing with smoke of dry ice in hot water.
I actually don't think that the sublimating dry ice will create that much CO2 density, The vapor that is seen is condensed water vapor do to the low temperature created by the dry ice.
Now you need to get some visible lasers out! Lasers look absolutely spectacular going through fog if you form a "fan" with the beam, seeing a 2d 'section' through the fog reveals all sorts of turbulence in the air currents. A piece of first surface mirror stuck to any kind of reciprocating mechanism will do for scanning the beam - I've used repurposed HDD head actuators, spindle motors or stepper motors fed with a repeating scan waveform of ~3v from an audio amplifier. You can also do interesting things blanking the beam at certain points in phase with the scanning signal to get multiple rays & bursts etc.

Careful with dry ice in a car. When I was a teen my work sent me to pick up 150lbs of dry ice. I loaded the three cubes in the back of my hatchback and drove back to work. Windows were up cause it was a 100f SoCal summer. 10 minutes into the way back I noticed that I started breathing heavy. Light went off in my head and I rolled down the window.
I mentioned that in another comment. A metric shit load of nitrogen will kill you as the body will only hyperventilate when the CO2 is high. High CO2 is the signal that O2 is low for your body. When you get that signal you get the hell out of there and go outside for air.
If you add a blower to pressurize the box you can get much greater flow. It's also worth touching on the oxygen deficiency hazards these are capable of creating. Short of those, that's a damn fine peasouper you've got there.
The larger capacity dry ice machines I've used have had blowers, but it occurs to me that they have significantly higher internal volume (and output). You make a good point, that a machine your size probably wouldn't benefit from it.
OooOooooooaoooh FOGGGMACHINES....🤩🤩🤩🤣 Man i am starting to wonder when there will be a video about the ever increasing collection of subwoofers in the background i’ve been drooling over for a month now..
We used to use dry ice fog a lot more often in theater, but it turns out singers are more comfortable with breathing a little bit of vegetable glycerin based haze compared to a lungful of CO2 which can really catch you off guard. These days, all the professional theaters use machines that blow standard fog/haze liquid over dry ice or even plain water ice to keep it low to the floor.
Post cooling a glycerin based fogger is a good technique. Breathing a ground hugging fog should be almost impossible unless you're located in the pit. Another small advantage of a pure water fog is that there is no sticky residue that eventually accumulates.
Cool! Maybe an idea to build a small unit that creates dry ice right when you need it with a couple of blasts of a CO2 fire extinguisher. Would be a serious challenge getting peltier elements or anything else to cool that low (would need a multi stage design I bet). Kind of would be a need addition to your previous (and this) project.
Hey, i always have fun watching your videos :) Because i learn a lot things the nice way ("This is the Way /Mandalorian) from you. Thank you and you and your family have a nice time. Wizzard Rincewind (Germany)
Can't wait till the how to 2nd video. I work as a dj on the side and was looking at fog machines. But they all looked too expensive and the issue of sticky residue is legitimate.
Looking forward to it! Do you think you can include instructions on how to safely grind the dry ice? Was there a reason besides convenience why you used wide-mouthed nozzles for the water delivery instead of narrow-mouthed or spray nozzles? Also, are you still planning to release your video tutorial on constructing the ultrasonic cleaner and ultrasonic emulsifier in the near future? Maybe a short video addressing production delays wouldn't go amiss.
Thanks for the comment. I will address the fine points of the design in a few days with the construction video. We will also cover the ultrasonic cleaner soon.
Are you sure it was dry ice? Your body reacts to the amount of CO2 in your lungs. Too much = signal for not enough oxygen = breathe more. Inhaling too much helium or nitrogen will make you faint. It was probably liquid nitrogen in the pool.
Is this documented anywhere? I'm not sure I believe this. A standard 20 lb block wouldn't even produce enough co2 gas to cover a hot tub with more than a few inches. This would require hundreds if not thousands of pounds of co2.
@@gizmoguyar Yes actually, it involved "around 30kg or dry ice" on Feb 29th in Moscow. They jumped into the pool after dumping the dry ice, the room was barely bigger than the pool. I've not seen an official cause of death but the video of them dumping it in is way too much for that space.
You should combine that with one of those smoke ring blaster things. Hmm.... I wonder if you could make a motorized aperture to control the size of smoke rings on demand?
On behalf of all the "Safety Sally"s... 'What's wrong with you?' As for the rest of us that understand risk/reward ratios AND personal responsibility, Thank you for sharing!
Can I please come and self isolate at your home? You are always doing so many awesome things and I would be so much more intelligent by the time I left! I could happily stay with you till Christmas!
Loads of fun potential! I wanna put one in my trunk, run the duct to a speaker port into the cab. Then activate it with the remote to my door locks and watch from a distance peoples' reaction as it fills the cab and pours out my tilt sun roof. My kinda fun!
