In this video I see if a non-waterproof drone can actually work and fly in de-ionized water! Since there are no ions in the water it should be non-conductive and the drone should still be able to work in the water and not short out! Will it actually work?

The RF Radio Frequency has a hard time going through water!
adinserter Radio waves have a hard time going through any good conductor. Basically, the radio waves get used up to induce electric current in the water which generates heat. This doesn't happen in de-ionized water as it is an insulator.
You realize RF stands for radio frequency right?
On top of that the weight of the water would probably keep it from leaving
I'm starting to realize that most of Action lab's viewers are dummies who don't know shit about science. Kinda disappointed.
@@sunilsoni3310 obviously, this is a dumbed down "lol SCIENCE BITCH" channel made for normies
Spends 5 min explaining why it wouldnt short circuit
Three drinks later:
9:20
It did not sort circuit btw
@@catguy7520 yeah i know
I was like... Just put the fucking drone in the water! That's why I'm here! lol
"It wont short circuit.
Wow i was sure it was gonna short circuit in there." Lol
No, he doesn't put that drone in a swimming pool.
Ohhh so clickbaityyyyyyyy
*CLICKS*
Well, he does put it in water, but in a glass vessel instead.
Dark Shade clicc bait
It would have been nice to recheck the water resistance after immersion to see if any ions had been added to the water.
0:15 Hopefully the deionized water will have such a low resistance that it shorts out my drone and kills it instantly.
lol, whoops
I was like wtf
Not even what he said
He said won't short the internal circuitry
Drew Graham he said that because action lab said low resistance, which will break the drone. Action lab should’ve said he hopes it has high resistance.
The internal computers felt the resistance in the motors and shut off just as you said. The light started flashing when you landed in the water so it's possible that it wasn't able to receive signal from the remote but I think these drones have to be set upright or on a flat surface after an auto shut-off to begin flying again. It also probably flew really weird when you took it out of the water because this drone has and altimeter which likely have water in it making it very difficult to read the air pressure and that's why it kept floating up to the ceiling.
Did he say he hopes the water will have a LOW resistance?
obvious blunder
Yes he was wrong
I was like. WHAT?
It was a f*** up between low conductivity and high resistance.
He's wrong
I had always assumed that the main conductive contributors when you add salt to distilled water would be the Na+ and Cl- ions. But in this video you're saying that those ions from the table salt really just allow the H+ and OH- ions to congregate in a manner that makes the water more conductive. Very interesting.
Yep it’s true, you don’t really want your salt to be part of the reaction, it just facilitates it
@@TheActionLab (thinks about it....)
Ah, right. I can see why you'd want the highly reactive sodium ion to stay paired up with the highly reactive chloride ion rather than skipping off and pairing up with whoever.
Now let me get this straight about the equation
There’s tire marks on your table?
Lol he drove over it
Damn that thumbnail is super clickbaity

What's most likely happening is that the remote is using a radio or an ir signal which bounces off liquids very easily so while it's getting a weak signal it should still work electrically, which we saw.
literally not even a soul:
the action lab: Can a Drone Fly in De-ionized Water?!?!?
3K people: thanks
Stop doing this joke its so dumb
No one:
You: come up with a terrible joke that has nothing humorous about it.
0:19 "such a low resistance"
Just a heads up
Very high resistance as there aren't any ions to conduct
Can something fly using vacuum I know sounds dumb but I guess deserves a try
It couldn't fly, there wouldn't be air to "push" but could jump.
yeah, you're actually dumb and maybe never attended a physics lesson. the only way to fly in vacuum is using the third law of newton. Throwing "stuff" in one direction with a N amount of force, will get you to experience the same force in the opposite drection. That's how we fly in space.
I love learning from your videos!!!
thank you for my science class today my dude, now i'll watch if the drone actually flies in water
Today's fact: The Flintstones was the most profitable network cartoon franchise for 30 years, that's before The Simpsons came along.
A Kripperino in this channel? But... Kripperinos are dead...
did you watch the video tho
@@TheActionLab hey umm great concept but would the same thing apply to a phone that's not waterproof??
@@grossio5564 i think that's impossible, just saying.
Take ur unrelated facts with u..
Hey, that would be a great experiment on radio frequency. To see how fast the signal deteriorates in water and other liquids. Just a thought.
Lot's of data on that already.
2.4GHz for example which is used commonly for RC control is significantly degraded over about 1.4cm of distance in water.
Lower frequencies perform better and commonly ultrasonic or laser connections are the ones which actually work effectively. Ultrasonic being the common method means bandwidth is very low, you could only transmit very small amounts of data.
Every title of the video you post make me go 'Wtf' at first, then they all make sense by the end of the video.
Innovative idea as always
Propel drones have a gyro takeoff sensor so it will not take off unless on a level surface
I think all drones that aren't absolute garbage do, it would be very hard to find one that doesn't if you want one like that on purpose. You can make it already "taken off" without really flying before submerging like he did later, having the drone slightly spinning before putting it in water bowl. I also think it only applies to first takeoff per each time the drone is powered on in most drones, otherwise you wouldn't be able to land on anything sloped and come back- it's just to calibrate the gyro before flight as it later calculates its angular position relative to that moment.
I would try again with a "wired" connection to the remote. RF and water don't always work well.
C Rodriguez unfortunately you can’t exactly buy a “wired” drone.. he’d have to make it himself
@@nathan07Has it ever stopped him from making something before? But yes I do see the complications.
@@nathan07 I mean he could build his own drone, use a wire transmitting an Sbus or PPM signal to the flight controller, and just have the radio receiver on a ground station
RF should be fine in deionized water. The problem with normal water is it’s conductive
There must be an over-current protection circuit that shuts down the motors do they don't burn up from trying so hard to spin!
Smrt man
I think what the system is detecting is voltage drop for the battery. The flashing lights is the alert for low battery power to warn users that the battery voltage has dropped below the safety levels. I have one of those little ready-to-fly models too.
Very good explanation of water & DI-water. I have same drone. Great inside/outside drone!
Can we intake more of the same food when it's cold than when it is hot?
thank you for the explanation
you're welcome
“I think it thought that it ran into something” yeah it ran into a bowl of water! 🤣
I'm a type 1 diabetic. I had no idea about this Know Labs product! Going to check it now!! Thanks for posting about it. Your videos are awesome, but I did not expect to find something such as this. An increase in value definitely. By the way, I work sort of closely to chemical engineers. I usually test what they product at refineries. Thanks again!!!
Oh my god i see this a day before my paper and this is one of the topics in my syllabus. Thanks man that helps
Love the awesome explanation at the beginning. It's a great balance of science to action. It means you don't have to fill up your footage with lots of dumb cuts to boring behind the scenes kinda stuff to get to your desired time.
Haha uhh nope.
It's probably all off balance after coming outta the water.
I would love to binge a condenced version of your vids. Seem like ypu're a great teacher, but around the highschool level. Wish my eng proffs were as concise as you are.
I have a question in regards to submerging batteries, I have a vehicle what they call a "Rzr" its an off road sport vehicle. The battery in this sits underneath the drivers seat. I regularly have it completely submerged in water crossings. Seeing that the water is "dirty" because of the debris flowing in the creek water. It seems like it would be a good conductor, why doesnt my battery short out?
wow that is so awesome, l love how much fun you are having flying it lol
For science
The reason it randomly started working when it was dropped in the water is due to the way the drone handles gyroscopic movement. Drone's at this caliber (haven't tested on the "pro" caliber stuff) WILL NOT spin their propellers unless they are below a certain tilt angle. When it landed in the bowl the first time it was on a steep enough angle that the blades wouldn't spin. The blinking lights on the bottom indicate two things, either this or, as someone else mentioned, low battery. Do this experiment with an empty bowl and the result would be the same...that is until the second part where it is less angled and starts working. In an open bowl it would fly right out, but in the water, the propellers pointed at the angled portion of the bowl generate more thrust either because of the way they are located or the inertia in the water of the heavier backside, and even though the drone tries to balance, it fails, and turns off. Then once it falls to the lesser angle, it starts working angle.
All in all..make sure you know all the "features" and how the drone actually works before saying that it didn't work. (P.S. it still might not work, but you would need a bigger, LEVEL, volume to test it in to be sure)
Side note: if he did do it in a pool and it didn't short, that might have worked
Except even the military cannot transmit radio thru water. With a bowl of water one can hope, with the controller against the edge of the bowl, to get a little transmission yo the stone but that's it if even that. The military used sonar because of this.
Would deionized water block the radio RF signal more or the same as then ionized water? and was that part of the initial problem?
i just learned more chemistry from you than i have throughout my whole year
Hello thank you for the interesting video!
I expected he'll put the drone in regular water in the end.
Of course! Me tooooo
Every time he said "pure water" I turned into a different Migo
I swear I learn so much more on this channel than school
Wait so I could technically say first.....
Well could've.
You make dopamine flood my brain!!
Pretty cool
i just learned more chemistry from you than i have the whole year
came here for a drone and found equations. Damn The Action Lab is always interesting :D
Reduce the prop size to have the same rpm in a thicker medium (water) compared to air. You'll have to adjust the pitch of the propeller to have similar lift capability vs rpm as well. It'll work, just needs a bit of trial and error.
just get a real quad with brushless motors

Lonnie Donegan once formed a Skiffle band with physicists.

I have the same hypothesis as you do. I figured it was resistance due to the propellers going very slow I'm the water.
I remember studying this more in depth in 6th grade
Ali0The0King that’s a lie
I have a feeling that the slowdown was because the water resistance was so high compared to air resistance. Maybe if it was a larger drone with more powerful motors it could overpower the resistance of the water. Now to find somebody who is will to try this with their high end drone. You should have also shown a comparison using 120VAC, we did this in Chemistry to prove the insulation properties of de-ionized water. 2 metal probes attached to wood 1 hot 1 neutral, a light bulb, switch and 120VAC in a circuit. Probes are inserted into de-ionized water flick the switch, light stays off. Move it to tap water hit the switch light turns on. The funnest part sprinkling ions into the de-ionized water and watching the light turn on. I forget what we used might have been NaCl.
What experiments can you do using an induction hob and liquids to produce electricity inside the liquids? Can you do anything that'll generate visible electric fields inside the pan used? I know they use electric induction to heat the pan used so could this be made visible using specific liquids with or without solids to arc to?
Actually, you can run a small DC motor (bare wire to battery) or a small flashlight bulb (bare wire to battery) under tap water. I learned this when I was 9 years old (20 years ago) by taking the off set motor from the 'Operation' game, wiring it to some AA batteries, and testing it in my bath tub. There, I also tested the same set up with a light bulb I got from a flashlight. DC won't totally short circuit... It's just the metals will erode over time and the battery will drain faster.
Your Chem videos are top notch. Stick to what you do best.
The radio frecuencys have a hard time on water and the gyro and accels use phisical things so when water gets in it messes up the gyro but when it dries if there is no residues it will work again
Does deionized water still register a ph if there's negligible OH?
Spoiler: It doesn't fly...
It swims.
We call flies flies because they fly but why didn't we call fish swims?
@@MuzikBike
Maybe you should ask the question the other way around:
Why don't we say that fish are fishing instead of swimming?!
*water* you talking about? You can't get electronics wet!
Correct me if I'm wrong, but I think that you swapped incorrectly the (+) and (-) : anode is negative and cathode positive?
I think part of the problem too is the transmitter and receiver radio waves being dispersed because of the refraction from the water and glass bowl. Which is why it started to work when you were closer the second time.
0:23 Actually that is false. You would want the resistance to be very high (unreadable) because that would prevent the current to flow and short out. The minerals in normal water have lower resistance which allows for the current to flow. The resistance in deionized water is very high (close to air) as air has unlimited resistance. You have to remember that current wants to find the quickest way to ground, and through that water is not the quickest way since the resistance is so high
You should do a video to test the accuracy of the know labs glucose band against a blood glucose machine. Just a simple idea
Wouldn't low resistance medium be exactly the cause of electronics short circuiting?
I don't know
It's not only the conductivity of the water which affects the circuitry but also the increasing of electric capacitance due to the much higher permittivity of water compared to air. Especially RF circuitry will suffer from "out of tune".
You need to try the cooling liquid. It will fly in it very nice!
the motors of drones are designed for air, and when the propellers rotate they displaces the air above them downwards and generates a thrust force oppositie to gravity and the drone lifts ups....as the mass of air is much less so the motors have low torque and higher rpm....
but when you put the drone in water... as we know that water is much denser than air so the propellers need to displace a greater mass of fluid in water than in air.... and due to the low torque of motors propellers are unable to displace the water and stops rotating..... if you remove the propellers and then put your drone inside water, you will still observe the motors rotating because now they don't need to displace any fluid....
in second attempt when you slowly put your drone inside the water the propellers were slowly moving due to momentum they possesed at high speed....
if you design a drone which has motor with high torque and high rpm both then the drone will actually move in water and as well as air.... ready-made drones won't because they are only designed for a fluid which has a density of air
i think u should do a video on capacitors dry vs wet
The first to click the notification
Is the one who learns things first
You should do this with a filming camera
I doubt it's the gyros/accelerometers that get messed up when putting it in water. It appears that it maintains altitude quite well so I suspect it has a barometer, which by its nature is open to the atmosphere so it probably got full of water and can't sense altitude so it just shoots up or falls.
You should try and use a more powerful drone like a ur65
(A brushless drone)
You should have uploaded this before my chemistry exam
_How much big explosion could a vacuum chamber handle?_
(sorry for bad English)
there is more science in this video than usual
The communication used by the drone seems to be IR which is why I guess it is hard to communicate. It will also be hard to fly drones that use IR in sun.
The principle works! But this drone is too small to push the water. I'd be interested in seeing how a bigger drone behaves.
my hypothesis (at 8:20 ish), i guess that, because the drone is not make to be in water, the material of the drone were kind of acting like a Salt inside the water, so it made the water more conductive that it was suppose to do. At 10:00, you talk about impurity. is it possible that the plastic/metal were disolving at a nanometric value that made the water ionized ? maybe with the electricity, it can act as a catalysis in the process ?
10:09 - That's true, and you even can see that the lights are still working properly.
This is why saltwater is so much more corrosive than fresh water.
Thumbs up to know labs too pretty cool invention
Drone gone prone 😂😂😂
This would be a sacrifice, but if you clipped each of the propellers to make them shorter (probably _much_ shorter), there should be less fluid resistance, and the drone should still be able to fly/swim because of the higher density of water.
Of course, the trade-off is that the drone probably wouldn't be able to fly in the air once it leaves the water. You'd likely need two sets of rotors for that.
You mean a really HIGH resistance.A low resistance means it can transfer electricity.A high resistance means it can not transfer current so good.For example plastic is not conductive because it has an infinite resistance. The lower the resistance,the better the material will conduct electricity.Anyway...cool experiment.Good job!
Low resistance or high sir...plz think that
Nice video!!!
But did you mean high resistance? (0:21)
What is the model of the drone ?
*Flies drone in water*
Physics: Wait, that's illegal!
Iron Man dies
Thank
It will work is Small electronic bits are not destroyed by water
Also hard time For radio waves under water
Over half of the video is explaining it's still nice to know
not sure you took viscosity into account. the extra load on the motor would likely make it think it hit something solid and freak out any protection circuits
What about the water friction with the propellors?
First part of the video just went over my head
How about cutting the propellers down so they have less drag in water?
U can tilt the drone at 90 degree ( 2 fans in water and 2 outside and Check it stopped due viscosity or some other reason
