What Happens If You Fly a Drone In An Elevator? Real Experiment!

Get your Action Lab Box Now! www.theactionlab.com/
In this video I actually fly a drone in an elevator to see what happens when the elevator goes to a different floor. Will the drone move with it or stay in its relative position? Then I also try to actively control the drone in order to see if I can keep it in control as the elevator is moving to the top floor! Then I talk about relative speeds and how this compares to flying on an airplane!

Hey everyone I want to address some comments I am seeing: 1. Remember that the drone is not floating in the elevator. It is not supported by air pressure or buoyancy. So even though the air starts moving down with the elevator, the drone doesn't care because the air isn't what is supporting the drone. It stays in place by the momentum of air thrown downward. So it doesn't matter that the air below it is moving downward relatively slowly or not, the drone will stay where it was hovering before the movement of the elevator. The results of this would be different with a balanced floating balloon in the center of the elevator. It would stay right with it for the most part as the elevator went up and down. 2. The drone does have vertical accelerometers. That is how it knows it is hovering with the correct propeller speed without falling. So even once the elevator air starts pushing the drone up or down while moving, the accelerometers try to keep it in place. So in addition to its inertia, the accelerometers are also keeping it in place. I didn't mention it in the video but it is a valid point to bring up. The drone would have an easier time staying with the elevator without altitude control (but that is basically what I simulated when I was throttling it).

[@Richard.Andersson]

I am pretty sure a small drone like that does not have barometer on it. However it probably has an accelerometer (and definitely a gyro), and it would be calibrated during boot and then be confused when you want to maintain a constant velocity (offset in the integral of the acceleration).

@@eseopu Incorrect. It got noting to do with the speed. Again - the helium balloon is floating up against the ceiling of the elevator. You press the elevator buttons so it goes down. Intuition tells us that the balloon would just be sitting against the ceiling not moving much at all. But it goes down! In fact if the elevator rides is long enough (remember - the elevator is going DOWN) - the helium balloon will sit on the floor! Same effect - take a helium balloon into your car. Let it float up against the ceiling in the middle of the car. Now step on the accelerator hard. Everything is pushed back -including you. But the balloon goes forward...why?

[@michaelmcchesney6645]

What I would like to see is what would happen if you started the drone after the elevator had already started moving, such that the drone had the same momentum as the elevator. It seems to me that it should be the same as flying a drone in a vehicle traveling at a constant velocity. It might be an easier experiment if you were in a taller building so that you had more time to start the drone and run the test while the elevator was moving. Of course, it would be necessary to run the experiment at a time that few if any other people wanted to use the elevator. I have a feeling that this video was shot after business hours.

It's depending on which sensor the drone is reading it's position. Acceleration can be measured, Air Pressure, others use the camera for fine adjustment (Phantom), and/or GPS. So in case of the plane, the drone might want to reposition to it's GPS position, which might geht hard on any plane.

The absence would be a theoretical box with an object within and nothing else whatsoever. So far as we test it, the acceleration force of the box impacts the object within, always. In other words, it shows that acceleration is gravity as far as the object inside and the box are concerned. And it holds true even if you add a gravity source outside of the box.

This actually makes for an interesting reversal of one of Einstein’s thought experiments regarding gravity. Instead of a man falling alongside the box (as the inertial reference frame) and the world outside moving, the drone and the world outside stay the same, and it is the box that moves. Either way it demonstrates that the acceleration of reference frames can create the illusion of force when none is being directly applied

[@pratiknaik6676]

It's interesting.I would like to know How does that apply on us? If I jump from a building what frame moves upward which makes me go to the ground. I have seen couple of videos which are not making sense to me right now. They kind of say that (hypothetically/theroritically) earth is accelerating at rate of 9.8m /s2 outwards. Making me fall inwards.(lift) is continuously going up making us fall every given moment. I will send the 2 videos after this comment. Share your thoughts. @Michael B

Great video experiment! It reminds me of that old thought experiment about the guy with a truck hauling chickens, though admittedly that thought experiment is often used to illustrate a different point. It's always a fun exercise to break down these kinds of questions/thought experiments by comparing how things look to different observers in different frames of reference. For example in this video, comparing the frame of reference of the human drone pilot, that of the drone, and that of an external observer with super x-ray vision standing on top of the building who can see everything thats going on in the system, (while not affecting said system). Einstein's theory of relativity says these reference frames are essentially all interchangeable and all valid, so I find that fun to think about. I would love it if you made a video with this footage and some of your other drone experiments, where you break it down "on a chalkboard," so to speak, walking viewers through the different reference frames, and how in some ways they may all appear "different" and yet they are "the same." Basically run us through these experiments and reference frames, helping viewers grasp the crux of what "relativity" is all about. When people hear the term "Relativity," I think they too often think of things like, E=MC2 and speed(limit) of light, curvature of space time, and other higher level concepts. But we need to remember that Relativity is also very much what it's name implies, basically that how a system or situation appear to an observer, is very much dependent on that observers frame of reference. Thanks for making these videos that help us think about all this good stuff. You encourage me to keep asking questions and learning, always.

Picture this, you've got your $3000 drone on a stationary airplane. You launch it, the plane starts to taxi, because of your advanced drone pilot skills you're able to stop it from crashing for a minutes as the plane slowly speeds up and changes direction. The plane stops momentarily and then launches into a takeoff run, hitting 300kph and rushing towards the end of the runway, you blink from the shock and hear a terrible noise as your drone is smashed to pieces at the rear of the cabin a second later.

Sealing the system would have a negligible effect. Also, not much air is escaping anyway, otherwise you would feel or hear rushing air when you're in a lift.

[@euerhenning5780]

Yes of course it will

[@jusjase_3229]

Yep, since the air isn't what's keeping the drone flying, but by the force produced by the propellers acting upon the air A balloon with neutral buoyancy should be different though On second thought, the balloon might need to be of negligible mass to remain stationary relative to the elevator. Should it have some mass, however, it'll likely behave similar to the drone, with less pronouced effect.

[@mariusfacktor3597]

I think this is more about inertia. If the elevator + air was moving at a constant velocity, the drone wouldn't appear to move. But it's the ACCELERATION of the elevator that causes the drone to go up. The drone has more mass than the surrounding air so while the air goes down with the elevator almost instantly, the drone takes longer to accelerate.

Isn't it more about the acceleration? Everything inside the elevator acts as a closed system, but it's suddenly acting in a >1g system. Youre able to control the drone better when the elevator has reached it's top speed, so it's not about the elevator moving up, it's about it going from 0 to X

Actually the same thing happens on the ISS. Every now and then they have to use small thrusters to keep it in it's correct orbit. During that burn, astronauts actually slowly get pushed against the wall, because of the increase in velocity. Thank you for sharing this video!!

[@DARK_AMBIGUOUS]

But everything NASA tells us is fake, they tell us that if you shoot a gun, the bullet leaves earths rotataion and it goes on an angle but we don’t see it because it goes so fast, that makes no sense because if then if you throw a ball in the air, it should fly to the side. It’s called the coriollis effect and it has never been proven to exist, in fact every single experiment fails to prove earths rotation

Just to point out. It only stayed flying due to the ground effect. You can clearly see it is not enough throttle to stay at the same speed as the elevator. But since it approaches the floor slower than the first time it has time enough to be affected by ground effect and stays airborne just by an inch. Great video

[@YoungMoneyFuture]

Cool experiment love your channel bro!

[@jespergran]

For everyone wondering why the drone is moving and not staying still: The acceleration/ g-force makes the drone move when the elevator changes speed. If the drone would have been launched after the elevator had accelerated, and stopped before it deaccelerated, the drone would have had the same speed as the elevator and therefore not move. It’s similar to you getting pushed into the seat in a car if you accelerate fast, and get pushed forward when the car stops fast.

[@g.narayanareddy1630]

What U said is true , if lift is horizontally moving to earth. But lift is moving against the earth, so even drone starts with lift. It connot be Still in lift as lift is moving up against gravitation force meaning lift requires continued force.

[@Agent_Ax]

Or in plain simple words Newton's first law of motion

[@sweeper7609]

If it was true the the drone would have start flying along with the elevator as soon as it hit the ground or celing. The drone is programed to move up/down up to a certain meter per second based on some kind of inertia sensor. The drone can't move at higher speed than X m/s, the elevator move at a speed higher than X m/s The drone crash at the ceiling if the elevator go down, and crash at the floor when it goes up.

[@sgtmontiel375]

Wrong, it’s because the drone doesn’t have GPS therefore not being able to hover precisely, hence the erratic movement

[@Ali1671]

it would be interesting to do this in an airplane to see when the drone loses acceleration and starts to move due to the movement of the airplane

[@PigRipperLAW]

Does the air in the elevator sink/rise? Why isn’t the air moving at the same speed of the elevator? Is it not all connected?

[@poisonwolf9859]

Yah like in a plane why is the air moving the same speed and isnt the plane also suddenly excelerating like my head man

[@Appletank8]

Once the plane is up to speed, yes. at takeoff and landing, air moves much like a fish tank being shoved around.

[@Appletank8]

Modern elevators tend to move fast enough and through shorter distances to not reach a constant rate.

[@my3dviews]

When accelerating upward the air in the elevator would get slightly compressed toward the floor and slightly compressed toward the ceiling when accelerating downward. That hat effect would be minimal on the drone. The main reason for the drone's movement is its inertia. When the elevator starts moving it tries to stay in the same spot, so ends up hitting the floor as the elevator accelerates upward, and hits the ceiling as the elevator accelerates downward. You would be able to hover it easily if the elevator had a longer travel time at a constant speed in either direction.

[@tank4969able]

[@DihinAmarasigha-up5hf]

[@theblockybanana5537]

The amount of air pushed by an elevator would depend on the size. Most elevators go about 1M/s, however this is a mid range application so maybe 2M/s. The amount of air pushed would be tiny, especially in the middle of the elevator.
