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.

0:15 Hopefully the deionized water will have such a low resistance that it shorts out my drone and kills it instantly.

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.

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.

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.

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.

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!

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.

Every title of the video you post make me go 'Wtf' at first, then they all make sense by the end of the video.

You make dopamine flood my brain!!

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

No rf failure

I have the same hypothesis as you do. I figured it was resistance due to the propellers going very slow I'm the water.

Wait so I could technically say first..... Well could've.

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

Would deionized water block the radio RF signal more or the same as then ionized water? and was that part of the initial problem?

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.

Every time he said "pure water" I turned into a different Migo

“I think it thought that it ran into something” yeah it ran into a bowl of water! 🤣

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.

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.

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

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?

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.

*water* you talking about? You can't get electronics wet!

Hello thank you for the interesting video!

You need to try the cooling liquid. It will fly in it very nice!

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

It will work is Small electronic bits are not destroyed by water Also hard time For radio waves under water

You should try and use a more powerful drone like a ur65 (A brushless drone)

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 ?

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.

0:21 "such a low resistance that it won't short-circuit" - I think you meant **high** resistance...

First part of the video just went over my head

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.

Over half of the video is explaining it's still nice to know

Low resistance or high sir...plz think that

Does deionized water still register a ph if there's negligible OH?

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".
