In this video I will show you how water and electricity/electronic circuits correlate by conducting a couple of experiments. Along the way we will bust a couple of preconceptions and find out whether we can use electronics underwater.

YAASSS NATRIUM!! Love using antiquity names for common elements!
Natrium and Kalium are German words as well. And as GreatScott is from Germany it's obvious, that he may use these words.
in german they are still called Natrium and Kalium, maybe that is the reason why he didn't say sodium :)
Calyo Delphi helium-helios I'm pretty sure
i was going to talk about that.
I would also think that his bowls are not clean enough to not contain any ions. even a little dust would be enough.
10 times bigger *writes 100*
Mistakes happen. Not sure why my script said 10 times.
GreatScott! No problem was just confused
Add a annotation about that. Simple :)
Sorry to inform you, but annotations don't exist anymore (at least in new videos, in older vids they exist)
In the eyes of the ungrateful, any mistake is unforgivable.
Thanks for the consistent and good quality videos.
Glad you like them
GreatScott! How doesnt like?
Captain Haddock
Blue Blistering Barnacles.
So, what we've learned today: Scott is left-handed.
Man, you gotta try harder! :)
I an left handed too
I though he was just avoid blocking the camera
You can see it in the intro
Bastian •, or Austria? But has anyone who ever heard him speak doubted that he speak German natively?
I'm glad to see you have "debunked" the myth of the conductivity of water.
At a previous job, I would load test standby generators in the range of 250kW to 500kW to assure the generators functionality using a "brine tank" as the restive load. This is a steel tank filled with about 200 to 250 gallons of tap water and an isolated copper conductor plate which was slowly lowered into the tank to increase current draw. Fully immersed, there would be near zero current draw between the plates when lowered into tap water. By adding about various amounts of table salt, the water would conduct electricity to the point the load could reach 100% of the rated load of the generator and the conductive plates would have to be lifted out of the brine to regulate the load being drawn.
Thanks for the great work you do.
No problem. And thanks for the feedback. Interesting story.
@@greatscottlab You should do a follow-up video, repeating this experiment with seawater!
*Short answer:* everything, but not really.
_everything,nt_
that was "well, yes but actually no"
A friend of mine once thought it was a good idea to use a humidity sensor continuously to see if his plants were getting dry. Didn't take long before the entire sensor had dissolved.
Really interesting ! I'm eager to see the video to make integrated circuits waterproof :o
Doesn't nail polish have acetone? would that not dissolve the solder mask and make the writings all smudgy?
UFOhunter Nope, it's nail polish remover that's made of acetone.
some nail polish actually uses some kind of plastic dissolved in acetone.
I'd use something llike polyurethane or epoxy, which can be bought for around 10-20€/kg.
You fill the case with apoxie or you spray it with silicone. Any number of things could have cheaply water protected portable devices. It’s criminal that it has taken so long when water is literally EVERYWHERE.
@@alexanderm9832 right so the solvent in nail polish is also acetone. Thus why it smells like acetone and can be wiped off with it.
DO a water proofing video!!!
J Wightman he said "But this is a subject for another video.".
Water is vary bad for ceramic capacitors. The dendrits is growing inside it. You can watch this beautiful process in the 1-st episode of Unseen World of Electronics. Some metals are dissolving and recovering again by electrolise.
Good one. I really like your drawings; they help the explanation beautifully.
Amazing video Scott. Keep making such videos
Me at 11PM: one more and I'm going to bed...
Me at 00:50: *this video*
At work I operate Wire EDM machines that use a fine brass wire to accurately cut steel and aluminum. The cool thing about it is that they do it with the part submerged under highly filtered water using voltages up to 300VDC. With all of the minerals filtered out, the water no longer conducts electricity. Although it is not recommended, you can stick your finger in the water and never feel even the slightest tingle.
More, more! Very interesting video, thanks :)
I was waiting for your upload in the last half an hour, worth it!!
Thanks for watching ;-)
Man I appreciate your passion for electronics. I was just thinking how much of your time you must spend making thse videos, and thank you :)
Too much time....
well I dropped my phone into toilet once, got it back in 5 seconds but it didn't turn on ever again. That's all the testing I needed to do with electronics and water.
FAQ: 1.) I took the battery out imediatly (because it was nokia remember when you could take batteries out of phones yourself, peperidge farm remembers) and air dried it overnight before attempting to turn on. 2.) it slipped out of my hoodie big cenral pocket, the one where you can touch your hand together even though they are in pockets, you know the type, yeah be careful with those.
That water had a *lot* more impurities than normal tap water.
Probably the poop that did it.
Well urine and stool both contain a lot of salts.
if fit falls into water DON'T TURN IT ON IMMEDIATELY
darius2640 I think that there was more than just water in that toilet...
You should make video waterproofing electronic. Use some clean coating. :) or waterproof really old PC and run it under water :)
You cannot make PC waterproof like that because it will overheat.
Nopparuj Ananvoranich it can be in water with fishes. and you can always under clock it
Check this video about Military computer.. czcams.com/video/55z_0BYb5is/video.html. It have some kind of varnish finish..
Nopparuj Ananvoranich Water is a pretty good conductor (of heat).
That's not true, lol. The heatsink doesn't need to be waterproofed, it's already waterproof ;) It'll cool just fine, maybe with an underwater pump or two to blow some water through the fins.
Awesome video as always. Thank you Great Scott!
Thank you! You always help me learn a lot. You also have very good quality videos.
Omg this video is so perfect! ! You are the best :D
"We will *conduct* a couple of experiments..."
Was that intended? :p
*Y E S*
I really like those close up shots. They look great!
very informative ... love your work every time...keep going
I imagine that the arduino in the distilled water started working once the ion concentration from your fingers diffused enough to raise the resistance of the water above whatever threshold.
Very good idea. I was waiting for this because i was too scared to try it my self so i was waiting a good video so there it is thanks😁😁
You're welcome :-)
Very informative and great quality! You’re channel’s great!
Today I watched this video as it came up in my feed and I thought that it's fascinating, thanks.
putting your fingers in the distilled pure water could have added some electrons so maybe that's why the aurdrino did he same thing it did in tap water. idk though because it started working again.
you're right
I comented the same thing
CalculatinGenius
I bet the arduino was a bit salty when his brother got a bubble bath
Don't try at home! Mains are dangerous with water. Great Scott you should advise as you already know people are trying same project that you make.
It is obvious that you should not play around with mains voltage.
amazing spiderman 0:12
Nothing wrong with a bit of natural selection.
burt1t0 thats what i always say before someone does something really stupid
You should go and watch BigClive's channel... then you'll see what fun can be had with water and electricity. Especially the Chinese electrode boilers, and electric showers that run cold water directly over live heating elements.
Great vid Great Scott!
This is what we call "taking one for the team". Thank you for sacrificing your own electronics for the benefit of the rest of us !!
Hey scott, could you build a breadboard-sized modular synthesizer?
Natrium is sodium in English. For some reason we use latin for the chemical symbol, so it comes out as Na.
Vyl Bird yeah I thought it was weird that he said natrium instead of sodium
Vyl Bird he probably says it cause in germans its called natrium too
Non-native speakers easily get caught out by uncommon words - sodium isn't something that you use much in everyday conversation.

Nice video, as always!
This was extremely interesting! THANK YOU ! keep up the good work!
6:29 If an Arduino hangs up, the reset switch won't work, you'll have to switch the power off, and then power it back up again.
Please make a circuit that safe shutdown for pi when a power supply goes off using battery (or) capacitor and provide power for 15 sec to safe automatic shutdown
Plz scott
Nice work bro..
Andreas Spiess made videos of this first with batteries, and then with super capacitors
czcams.com/video/m20o3P-S5s8/video.html
Wow..! I had this question in my mind for many years. Now its answered. Thank GreatScott.
Really nice work, man. And really interesting!
You sholdn't put Your finders in the destilled water because the Ions like the one you sweat dissolve from your skin into the water. And so the resistance gets much lower.
The current flow in the distilled water is caused as you have made contact with the water with you hand. You see, sweat also has ions and can make the distilled water conductive
that's what thought
Yeah, distilled water has resistance in range of several Mega Ohms
While pure water does have a rather small electrical conductance, would it be blasphemous to suggest that distilled water does not, with absolute certainty, contain any ions?
Even the vacuum of space contains a countable average number of hydrogen atoms in a cubic meter.
Great Scott, Great video
Very impresive. Nice video
And this is why water cooling setups for computers recommend distilled water rather than tap water.
I think water isn't just good idea for cooling. It has rather a low boiling point for high power PC.
It doesn't stay distilled for long.
The usual cooling mix for computers is distilled water plus ethan-1,2-diol. Plain antifreeze, as an antimicrobial. You might think the water is devoid of nutrition, but the algae somehow find some anyway.
GreenMC in don't Think anything in your pc should ever reach 100 degrees celsius
Kevin Rabe I'll agree with you, but even at lower temperatures water will slightly vaporize, so some alcohol mix would be better.
GreenMC wouldn't alcohol evaporate more quickly?
Last time I was this early...
I never was...
Great video ScottyBoy ❤
Thanks
Wow! Nicely explained! Very informative! 👏👏
Very informative and entertaining video again. Thank you.
Awsome Tutorial Dear Scott!
Am your Biggest Fan Love U From Pakistan
8:09 what kind of "coating" is that and where can you buy that?
It is Nail polish.
Genius experiment. Thanks for the great content !
This was super interesting! Thanks for the video!

Was that “conduct” pun intentional?
I have a question for you.
My computer is/was watercooled, radiator sprung a leak and drenched the 1000watt psu in coolant, and it let out a HUGE bang and took out both the cirquit breaker and the main circuit breaker in my house.
Would it be possible to fix something like this or do you think it's a waste of money compared to just buy a new?
StopaskingformynameCZcams don't risk it. Buy a new one, power supplies are dangerous
You can repair it, if you are lucky maybe it will be easy, but only do it if you have enough experince with power supplies...
If the power transistors are shorted on all 3 pins, don't try to fix it. There will be many other faults and it will be very difficult to fix.
THIS is the reason why I think watercooling is retarded.
Watercooling is retarded.
But it was fine for 5 years tho.
Kept my system at 40C while gaming and made allmost no sound.
But i guess if you're doing watercooling, radiators should be changed after a few years just in case.
well done Scott!
very intersting video.
Thank you my friend!
Wonderful work..
Thanks
1:25 MAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAATH!!!
I could be wrong, but he write ×100 and said ×10
He meant to say 100, saying 10 was just an accident
How could you possibly be wrong? You can replay the video if you're not sure...
I love these electronics videos!
I love your hand writing.
Water Proofing Electronics!
Soon....
GreatScott! Will be looking forward!
You should've tried sea water too, just for fun :)
I ruined my phone in sea water ):
did u revive it?
No, but I tried a lot. It was supposed to be water resistant (Moto G4 Plus) but i think it's idiotic to put a non-removable battery if you want it to be water resistant.
He could just dump 100g salt and conducting would have increased along with corrosion
Thank you. Good work.
Thank you for posting this.
By the way, the second Arduino in the distilled water likely stopped working because the water would have dissolved any residual flux on the surface, increasing conductivity right at the surface of the Arduino. Once the dissolved flux remnants dispersed over a larger area, the conductivity would have dropped back down.

Do u mean /kill?
Great video, thanks!
Nice information, great video
3:02 the direction of current is the opposite of the direction of electron flows
Electrons move from the negative to positive outside of the cell. Positive to negative, inside the cell.
Finally someone noticed.
Arduino stop working. With water disabled oscillating crystal!
yeah I wonder what actually happened to the arduino. those pro minis have ceramic resonators instead of crystals, but I dont know exactly how a ceramic resonator works. are they just like super accurate r/c oscillators maybe? idk
You are correct sir. Crystal oscillators are very sensitive to resistive loading and by submerging in conductive water you effectively add a ~30k ohm resistor across the two terminals. The crystal cannot drive such a low impedance load and fails to oscillate.
I believe the restart of the oscillator after some time is due to chemical deposits forming on the exposed metals that form thin insulators and raise the resistance up to a point where the oscillator can operate. A quick reset and off it goes.
A step toward future electronics.
Great video 😋
That was genuinely interesting, thanks!
You are a genius!! I love your videos thank you! So if I put my knowledge to the test, why are people so scared to drop their iPhones in water if it doesn't necessarily ruin it right away?
If you get it out of the water, disconnect the battery and dry it, there is a good chance that it will survive.
You ruined the distilled water test when you put your finger in it. Just saying.
Well you also ruin it the moment there is any metal present...
MsSomeonenew wrong. Properly distilled water is not conductive
That is a really interesting video! Thanks
These are really amazing videos :)

Just realised I can like my own comment!
That was awesome and Useful!!
Your videos are always amazing... Keep it up
The shot of the capacitor under water was fantastic
Very interesting video. thank you.
From your videos, we learn a lot
Thanks
Awesome!!! Great quality!! Nice content!
Thank you very much, this is a very good quality, informative video.
Thanks for sharing 😀👍
Very nice and informative video!
I'm looking forward to the waterproofing video.
Pretty interesting Scott, thanks for this video...
Very informative video indeed... Thank you very much for this!
Best video..thank you Scott
Thank you for this knowledge!
Once upon a time, when I worked as a control tech apprentice for an Asphalt Plant manufacturer... the official way we remidied dust/smoking plant operator problems with computers was a water hose. We were usually doing major controls upgrades that took weeks. So long as all the water had time to completely dry from around IC's, we never had problems.
A computer's rear mounted vacuum device often branded "Cooling Fan" causes big problems in an industrial environment. I've seen old PC towers that were 80-90% full of dust munchkins.
one of the best videos!
Exxtremely interesting video! Thanks !!
Great Scott you are truly Großartig!!
This video reminded me with an experiment I did any years ago. I dispersed graphene nanoplatelets into a dielectric fluid to increase its thermal conductivity (way less than 1% by weight).I placed a computer power supply in the fluid after checking the electrical resistance of the fluid which was to high to measure, before and after adding the graphene. onceI powered the power supply, it smoked. I couldn’t understand which components failed. You should try this experiment with graphite in oil. You might figure out the cause of such failure. Thanks you for great video.
Acquiring items off of the curb is only half the fun as I always plug them in to see if they still function. Usually they work to some extent and they never flame out like on tv. Maybe I'm weird but it's entertaining to watch a tv with water running out of it. Great vid as usual!
Awesome video!
Hammer Video!
I like your videos thank you soo much just carry on and we support you.
