English mate....english would help.

ahoj, dve otázky na teba mám. 1. odkiaľ si kúpil ten prikvapkávací lievik, 2. čo za piesok si použil/odkiaľ ho máš? Ďakujem

you distryied the coil with them screws .

Kitchen cutlery has 18% of Cr. It is scary to think about chinese stainless, because it rusts on the air. does not even need Cl.

It Is fast

Are the coils delta or strar?

When i added HCl to yellow solution of sodium chromate, instead of dichromate i got colorless solution...

Still, an instructive clip. I've done something similar using ferric chloride as my chlorine source. I too am careful with such reactions. A very famous rx about getting FeCl3 to about 70 C or so to etch copper clad circuit boards. Works pretty good with other stuff too. A lot of sitting around watching your thermometer and picking your teeth, so to speak. Well done.

Do you have the plans for it available?

Here is one. Aluminum electrode, water and AC

I first subscribed for your chemistry... amazing what else you have showed us as the years go by! :) Thank you for adding the term "shit manifold" to my vocabulary. 4:15 you need a good, strong seal on sewerage pipes! ... ... ... BUT! ...

never heard about propane being used as solvent. such a wonderful video

castner keller cell cool

From uk southwales brilliant video and cheers very glad

so what is size of the particle and morphology ??

Well, kinda unexpected quick update (23.3.2024): I forgot to mention in the video, the main reason why I went to neurologist - I've got an exploding head syndrome (LOL, but srsly look it up). Pretty harmless stuff apparently, but frightening as hell. Anyway, looking at some more literature, I found thing called "Sleep inertia" which I called paralysis. Could me more issues combined still... But the symptoms match quite well, and I can imagine severe cases actually causing severe issues when waking up. The sleep inertia is supposed to be caused by adenosine buildup, so that should be testable at least. In conclusion, it seems, that I am seriously fucked. Like having that much disorders in one particular bio/mental function would suggest to me, that something must be obviously wrong. But, I went to MRI, and mechanically, all seems to be OK. There is one thing that comes to my mind: When I was young, I did bite a wire that was live (240V). I lost consciousness and woke up screaming, which would suggest to me, that my heart did restart. this felt, like I was shot in the head (whatever that feels like, I would say it has to be pretty close). But on the other hand, I am pretty sure I had issues before that happened... Final note is that I will have to stop valproate experiment for next 6ish months. This is because you can't fly while using it. Was trying to get exception due to low dosage, but nope :/ I may try to check if valerian root extract contains any valproate (which I was allowed to use). Also the blood sugar test. But mainly will see the effect of stopping valproate usage. Update #2 (24.4.2024): I was busy moving to new location, so I had to prolong normal sleep cycle as much as possible. The date from this period clearly shows, that the paralysis intensity got much worse after I stopped using VPA, but question remains, whether this would happen anyway... In any case, this should be replicable. As paralysis intensity increased I have noticed, that my speech was getting more and more slurred after waking up to the point, that I almost wasn't able to speak. As I have technically completed moving essential stuff, I have stopped using alarm clock so resumed natural sleep cycle. Don't have much data still, but speech seems to be much less impaired after waking up now. This can be another "objective" metric that can be tracked. Similar to the speech slurring, I have experienced increasing eye redness. For now these seem to be highly correlated also subject to more research. This is very weird, but I feel like this amount of clues should get us somewhere.

Hello merci pour votre présentation, par contre je n'ai pas retrouvé la référence de vos leds

Remember kids , just because you know basic chemistry doesn't mean you can't completely retarded.

how to transfer chromium finish from cutlery to other objects?

How much voltage is applied?

Can we sell it?????

hmm zajímavé :D

If you bake a dense mixture, it will break due to repeated septation. Is there any way to secure this?

Would love an update video on this :) If you have time

How to rewind the motor it so simple

For those who want to make it: 1. You need a kiln heated to 800-850 C (you have to play with temperature 2. You need a mould (iron or stainless, quarz pipe pease wolud wirk, but never tried 3. Glass shall be ground on a ball mill and seived to size, depending on the porousity you want to get. 4. Put the frit to the mould and compact it (with beaker bottom or something. 5. Put the mould with the fritt to the heated oven for 5-7 minutes, but you have to play with time a lot to get good result. 6. Take mould out and cool on the table, remove glass when it is still hot. You may use some talc to make tge mold less sticky to glass

How's your experiment going ?

This reaction produces sodium aluminate but how did you got aluminum hydroxide?

and also decrease the temperature 0 c°C is good but -20 °C is better

Can you make a video to make magnesium powder using magnesium chloride??

i have two suggestion: 1 use an aquarium porous stone immersed in te solution to increase de surface area between gas and liquid phases. 2 ad Thiourea to the solution , will help to reduce over oxidation and to convert byproduct in to haldehyde.

the only gas that can weld steel is acetylene....

Cool. I wonder if it can be used to make gems with like the alumina made from crushed corundum. Also, to get rid of the sodium salt you can wash your ceramic with water. Mix it with water, let it settle, pour off the top water and repeat until it isn't salty. Then dry the ceramic.

im just making it by electrolisis of a dissolution of distilled water and sodium chloride :-/ (metal negative carbon positive) (ps: i also used this method to make copper oxide)

Do you have a procedure to extract resin

Do an AC scrub to remove chlorophyll t hen filter through DC

That little Ryobi drill deserves a medal, wow! 6:29

Thanks for a follow-up video!

Perfact!

Parabéns pelo trabalho de qualidade!

This isn't really helpful, but even though the vapor pressure of benzaldehyde is low, the amount of gas you were running through it for that amount of time was probably enough to evaporate most of it as quickly as you were making it. I've had this problem when chlorinating hydrocarbons where the huge amount of HCl produced is enough to carry away most of the product. For me and for what I was doing, a dry ice gas trap worked. That probably wouldn't work very well for you though without at least a gas drier before the ozone generator or you'll get nothing but water ice.

It can build on the electric car

it loks like you are from czechia

Problem is you need 4to 6kw to weld!! If you hook up a high pressure tank that builds pressure up to 90psi then you could weld! JUST MAKE SURE TANK IS STATIC PROOF! AND YOU HAVE LIKE 3 BUBBLERS AND 3 CHECK VALVES!! OR ELSE YOU WILL BE BUILDING A BOMB!!

🤣🤣

if you put glycerine in that, u will get flexable glass.

You can use breaking if you install a break chopper. You would need to mess around with a comparator and a power transistor on a heat sink or you could use the analog inputs and a PWM output of the arduino. Let's say you connect a voltage divider from the power rail to the A1 of the arduino. If the supply rail is increasing over the safe voltage, you start ramping up the PWM to turn on the power transistor across the supply rails (with a load resistor) and dump it as heat. That's exactly what industrial VFDs do when DC breaking.

"They say the previous owner was an electrician" You've done this to yourself. I'm an electrician. If the seller told me a house was owned by another electrician I would say goodbye and get in my car.

When you said the previous owner was an electrician... I was expecting EXACTLY WHAT YOU FOUND. ;)

Interesting spiderweb you encountered there. Layers upon layers of "improvements" every decade, until it all became a tangled mess. Not just the electrical, the plumbing looks like a mess as well. - Good you are rewiring the whole house. Probably much safer and much easier to maintain.
