It would be interesting to try again with your Mavic Mini to see if it's downward facing sensors will try to maintain its distance from the floor. The whoop is acros right? So it's going to keep its position relative to floors in the elevator shaft and not move with the elevator. I think the Mini will maintain it's distance from the floor as the elevator travels up or down it will compensate.
VERY FUNNY VIDEO KEN!! ... But Ken, what about a stable hover while going up or down and then see what happens when the elevator stops.. Maybe i'll try that and ill post the results 😀😀
I was not expecting that either lol... nice idea, probably more risky with a larger more steady drone, like the Mavic Mini (with prop guards on of course) but that would possibly show it even better being more 'stable' before the lift moves, great video as usual 🙂👍
@@KenHeron Ah yes of course, didn't think of that, btw great details also in the video explaining why, thanks for the reply (my wife just said "you have a reply from your mate Ken" lol)
The drone does move with the column of air however as the elevator begins moving the column of air is independent of the elevator and doesn't move until acted on by enough forces of the elevator that contains it. If the elevator trip was long enough and the drone was launched after the air was moving with the elevator, the drone would hover.
@@steelsurfercore5642 oh that's easy, the earth is flat. Nah unlike helicopters fixed wing aircraft depend on velocity to create lift. Helicopters rotate their wings to create a column of air they ride on top of, hence they can remain stationary. Since the plane gains velocity within the frame of the spinning earth the earth's spin has minimal effect. It does however have an effect that must be taken into account on long voyages.
If the elevator was sealed it probably would follow the more than it does other wise. It the same reason your ears pop going on an elevator. You have air entering and exiting the elevator as the pressure changes
It's almost no different than if the drone was hovering next to the elevator although when it gets close to the floor the air pushes of the floor right?
Fun video Ken, quick question though. Wouldn't the column of air actually be located on the outside of the metal box/elevator? Since it's the elevator that is the means of displacing the air as it moves? Doesn't matter it was nice seeing DANA.
Very cool experiment and I super loved your animation. is that after effects? I think your drone hovering is an object at rest and it tends to stay at rest when the elevator moves around it. The rising or falling column of air in the elevator does tend to lift the Drone or drop it but the drones inertia is a stronger Force.
Hello i am danny damveld from the Netherlands and I have a mavic mini and i see this video and i have a idea, and a mavic mini hover better stil in the air than that little drone you use , so why not trying thesame trick with the mavic mini in the elevator to hovering but than with prop guards on it. I am very interested how that works. Greetings danny damveld from the Netherlands.
i agree they should have tried it with a bigger and more stable multirotor like a racing quad with stabilization.. but i guess the reason why is because a mavic is a bad choice have sensors on the bottom to allow it to hover over the floor.. the sensors might fudge the result.. i also suspect that an "airtight" elevator would have the multirotor follow the coloum of air inside and hover where he put it.. but such an elevator would be an unpleasent ride as your ears would pop every time you ride it a few floors
Inertia is related to mass. An object will only change inertia (move) if a force is directed upon it sufficient to accelerate that mass. So whether the flying object moves with the elevator (or car or truck or plane) is related to the force caused by the mass of air around the flying object pushing on that object. A fly would be relatively light as compared to the block of air. So the moving of that block of air would be more likely to move the fly (though I'm sure also that the fly would be sensitive to the change in acceleration and compensate, like a drone with downward facing sensors would). Imagine instead if the elevator was a tank of water and the drone was just 'swimming' in the middle. The mass of the water would be much more close to that of the drone and thus the water moving would 'push more' (transfer more force) to the drone and thus move it up/down also (would appear stationaty to you in the elevator). Taking this further, if you had water in there but a 'really heavy drone' the moving of the water would not move the 'heavy drone' as much. Experiment with different size drones and see the effect of movement in the elevator. I bet a more massive drone would stay still (appear to move) with greater effect than a small one (but then you have to deal with the 'spinning blades of death'!). (sorry dude hadn't gotten to the physics part of your video when making my long-winded comment-- totally did the water idea I had as well!)
I think it will depend on the drone. The one used here was probably relying on accelerometers for stability (this jibes with the physics lesson). If it used optical flow sensors to reference the structure of the elevator, it would move with it.
Good Job Guy's. Now try it with say something that has optical flow lol..the only thing is there's not enough room. That would be great to see as well ☺️
And here’s another physics teaser changed it for sake of channel to “drones”. If a drone crashes into an inanimate object (wall) at 20 mph it will suffer “x” damage. If two drones crash into each other head on at 20 mph what would “x” be. In other words is the damage as if the first drone crashed at 40 mph. Two drones travelled Ng at 20 mph collide is it like hitting a brick wall at 40?
Yes, assuming both drones have the same speed, mass, and durability. theoretically they should both dramatically change their acceleration at the same rate, and drop straight down.
Ken Heron is correct. The drones, being plastic, will have considerably more give than the bridk wall and the damage would therefore not be the same as a 40MPH crash with a wall. Still, if you want to do the experiment, I’ll watch. :)
No the answer is it is the same. It is not accumulating forget light weight drones. Myth busters demonstrated the physics. And it surprised them. A car hitting a wall at 30 mph suffers the same damage as two cars head on going at 30 mph each. It is not as if they hit a wall at 60. And Ken I bet if we give this to that bloke in England he’ll make a brick drone. He’s made some incredible flying machines.
You showed Newton on your thumbnail and you referred to his 2nd Law of motion. However, Einstein and his general, and Special Theories of Relativity applies. The simplest demonstration of your experiment would be to apply Einstein's train thought experiment, and consider your position, and the hovering drone's position in that experiment. Consider that you in the elevator with your feet on the floor would be one element of the experiment, and the hovering drone a separate element. The Einstein train thought experiment involves a moving train (at a set speed)with two individuals at each end of a coach throwing a ball to one another. What happens in the experiment is what each of the ball throwers/catchers interprets as the ball speed and motion, and what an observer would perceive to be happening from outside the train. The roof & the floor of the elevator would in effect be each end of the moving train. All good fun and very interesting.
Wow, finally I've descovered a sign of intelligence on Ken's Channel. Thank you so much, please advise Ken to drop the face circle of his silly face from the channel. He is losing new subscribers, who know him with the mask😃😁

I knew exactly what it would do and a fly does move backwards as you move forward it just compensates think about what happens when you slam on the breaks even things that don’t fly do
Hi Ken. AEROSMITH BABY... ! 🤘😎🤘 It's opposite motion, there's a similar experiment involving a wig wearer in a convertible - the wig flys off, but goes forward into the windscreen (or wind shield - a little UK to US translation for ya, which is all part of the service 😏👍). Due to air pressure difference and vortex and stuff. Cool experiment, science with Ken should be a thing
That pressure will change though as the elevator goes up. In a closed elevator, it will have its own controlled climate. The sensors will read the barometric pressure to the floor. The question is will the drone adjust to compensate when it goes up, or down.
Mike Miller the drone doesn’t go up or down. The elevator goes up and down. The drone maintains hold at a set baro and so it appears (if the elevator is going up) that the drone is dropping to the floor. Don’t quite know what you mean about controlled climate.
@@punapirate interesting debate, if you try to land your drone at a altitude higher than what you launched from, it wont just slam into the ground, the drone will sense the baro pressure between it and the ground and slow down to land. i think the same thing will happen in the elevator. as the elevator goes up, the baro pressure will change, the question is, what will the drone do? i think it will compensate and go up.
@@KenHeron I've seen an older video of yours trying to fly inside a truck !!! (you are so crazy !!! 😊😋😊😊)Thank god nothing happened tο the phantom !! 😊😊😋 Keep up !
do the same experiment with the drone, in a hermetically closed environment, leaving the drone hovering statically in the air for at least 1 hour. If the drone doesn't hit the ceiling, floor or walls in that time frame, IT MEANS THE EARTH DOESN'T ROTATE.
What you just said is absolutely incorrect. Drone will only hit the ceiling floor or walls if the earth starts rotating FASTER or SLOWER. if the rotation is the same speed it will not touch it. Imagine a moving car, you can't feel the speed, only accelerating or changing direction or stopping starts moving you to the ceiling floor or walls of the car
I think those things work by barometers, which measure pressure at certain levels of altitude. I expected it to maintain its hight relationship with the real ground. Since they accelorate or decelorate depending to maintain that pressure, I don’t think Newton’s second law is the determinint factor. The movement is influenced by the rate of propellor spin, and that’s a different story. But still, it was a nice hallenge. :). I’m for anything that makes us think. :) How many thousand dollars do I win? “)
Oh, wait. I missed that his was an unstabilized craft. If that’s the case and absolute, my argument doesn’t apply. I apologize. But we cannot ignore the fact that we have a unit that is trying to maintain a zero gravity, as opposed to something resting on a “layer” (only an analogy) of air. Personally, I always thought these craft.- even the “unstabilized” ones - had some semblance of actual altitude. Silly me.
Would be curious what the mavic mini would do with the ground sensors, would it base the distance off the carpet or does it use barometric pressure when it can’t see satellites. Doesn’t Dana have one of those 😉
Three hundredth ! Everybody gets a First but I just got 300th !! YAY ! Ok now that I'm over myself that was a pretty cool experiment . Stay safe , stay well and keep bringing the fun !
Pull the old cargo dropper out and see the difference in hanging the object to be dropped by rubber band versus solid string.... i assure you you will see something Interesting
@@KenHeron yeah you're probably right. and that's if you even got a lock in the elevator. but there are other means of position holding. although i can't think of one that wouldn't be effected by its physical surroundings. It is a difficult problem with the choosin tools
I think you'd have more reliable results if you used a more stable drone (e.g. Mavic) rather than a cheap Whoop. The experiment needs to begin with the drone hovering as steady as possible, and not jumping all over the place.
C’mon you really thought the drone would go with the elevator?! YOU move with the elevator because you are in contact with it, and...gravity. Lol. But hovering, it doesn’t KNOW the elevator moved and no extra forces acting on it so of course it will remain hovering while YOU move. Now, what if you hover on a bus that is traveling at 55 mph, and then you fly forward. Is the drone moving at 70?! (Yup)
Oh yeah! I saw that already! Haha. By the way, I think your videos are just great and you are one of my favorite drone personalities. Great sense of humor.
That was a crappy drone to test with, was it not? It could not even hover steady when still. And you are incorrect about the air and water difference, if it had been air tight it would have been pushed up with the elevator the same way as with the water had pored out if it was not water tight. The point is that there is a flow of air and some of the air is exchanged (slips in/out) so the air is not pushed the same way fixed material is. But had it been an air tight/sealed environment (like a pressurised airplane), it would have been different.
It's actually the best drone to test with because it's small and not stabilized. Also, you're wrong about the air. Air pressure has nothing to do with mass and drag. Thanks for commenting though!
Now THAT is what I call proper consumer information, and this is why you are a genius
Do it with your P4.... and prop guards 😂
The video you did a few years ago in the back of the truck was great!

Someone may have mentioned this, but it's the accelerometer that is keeping the tiny quad in place as the elevator moves up or down.
Haha, I did this a year ago, many didn't guess correctly what was going to happen!
Did you do it with a drone with barometric sensors? I'm having a debate now with several people about what would happen.

take a helium balloon on string in a van and drive you will see the air move in the car same with smoke. You drive forward so will balloon
Need to try it in a car
Link in description. 👍
I think you'd have more reliable results if you used a more stable drone (e.g. Mavic) rather than a cheap Whoop. The experiment needs to begin with the drone hovering as steady as possible, and not jumping all over the place.
Any GPS/sensor stabilized drone would've negated the test.
@@KenHeron I wasn't aware of that! Thanks, Ken.
You betcha!
C’mon you really thought the drone would go with the elevator?! YOU move with the elevator because you are in contact with it, and...gravity. Lol. But hovering, it doesn’t KNOW the elevator moved and no extra forces acting on it so of course it will remain hovering while YOU move. Now, what if you hover on a bus that is traveling at 55 mph, and then you fly forward. Is the drone moving at 70?! (Yup)

Oh yeah! I saw that already! Haha. By the way, I think your videos are just great and you are one of my favorite drone personalities. Great sense of humor.
Sensers might change outcome
tom peppin t.v. Sensors caused the outcome. The overlooked part of this experiment was that the drone is actively trying to maintain an altitude.
That drone had no sensors i do not believe, just self leveling
No sensors like a mavic 2 pro.
That was a crappy drone to test with, was it not? It could not even hover steady when still. And you are incorrect about the air and water difference, if it had been air tight it would have been pushed up with the elevator the same way as with the water had pored out if it was not water tight. The point is that there is a flow of air and some of the air is exchanged (slips in/out) so the air is not pushed the same way fixed material is. But had it been an air tight/sealed environment (like a pressurised airplane), it would have been different.
It's actually the best drone to test with because it's small and not stabilized. Also, you're wrong about the air. Air pressure has nothing to do with mass and drag. Thanks for commenting though!
@@KenHeron Heh, ok
🤓👍
GPS lock on the drone???
Any GPS/sensor stabilized drone would've negated the test.
@@KenHeron what does negated mean! Please remember most of your subscribers are*** down home country folks****,,,,😅😄😜🤪🤣😋🤪🤗
