Very interesting experiment. Instead of measuring the amount of weight reduction by trying to take off and fly, spin the fan backwards and press it down onto the scale to see how much force it is able to apply. Then you could grab some statistics like how much power it takes to generate a certain amount of lift. Be curious what that curve looks like.
If the scale and motor had a small scaffold, perhaps made of heavy duty aluminum foil with a hole punched through it, positioned just under the propeller and resting on the floor of the chamber on 4 legs positioned around the corners of the scale, the downward thrust could be deflected and an accurate measurement taken.
you could also put the wheigt on a hanging scale...?
Though for more accurate testing nasa used a device to simulate mars gravity by using cables that lifted the ingenuity enough to counteract the extra force earth applies.
Bu this is s good experiment he did nonetheless.
Dontcha just love outside the box physics..simple smart application...cudos
I had no idea atmospheric pressure in mars was THAT low, ingenuity is much much cooler now
Well, once the pressure drops , the T also
is dropping, sooo vacuum is cool by default 🤣🤓
@@MrPILI86 what about radiated heat?
@@MrPILI86 Well the temperature drops if the pressure drops, but if the pressure was always low, then that isn't the case. Changes in pressure change the temperature, but low pressure doesn't automatically equal cold.
That's why u should be interested in space
@@DANGJOS what I’ve written was meant to be kind of a tongue in cheek remotely scientific pun. Judging by the comments , I failed 🤣. Of course once you are changing the volume of the gas , the relationship between pressure and temperature is not as I described it ;)
Neat experiment here... really shows the power of Ingenuity!
Side Note: Using the meter and the vacuum port as terminals was genius!
😂🤣😂🤣😂🤣
I just noticed the way he did it! So smart!
@@frankh.3849 why tf are u laughing?
Smart smart .....he don't have a clue
Spark plugs work too
Really interesting that because there was very low air drag, the blade kept spinning for much longer inside the vacuum chamber as compared to if it were outside
Maybe the blade has a circle surrounding the blade and idk what type of blade that is
@LabRat Knatz The sun already does that!
@LabRat Knatz The moon would be better. Closer to earth for maintenance etc, and alot more sunlight than on mars.
Thats also why it didn’t launch
4:23 This is why CD-ROM drives stopped around 52x speed.
cd=4.75in x 3.14 pie = 14.915in circumference x5200rpm =77,558 ipm x 60 min per hour =4,653,480 iph divide by 12 inch per foot = 387,790fph divide by 5280 feet per mile = rim velocity of 73.44 MPH. Its funny some people think with the earth's rim velocity of 1040mph at the equator, all the oceans sand and loose things just stick to the spinning ball. LOL
@@tadpole0690 where is your proof of the BullSh*t story of the pressurized, spinning, water covered cannon ball, whirling, twirling and hurtling simultaneously in four different directions at a combined speed upwards of 2million MPH through the infinite vacuum of space with no physical barrier between, spherical Earth Theory?
@@tadpole0690 must have been an intense odor
@@In_Rem What's the angular velocity of the CD compared to the earth? Flattards don't like to talk about angular velocity IME, it hurts their retarded claims quite badly.
@@ferrumignis Take your angular velocity with you to the center axis of a 3963 mile dia. disk placed inside of a ring with an inside dia. of 3963 miles 1ft for clearance. Ok, start rotating the disk up to an angular velocity of 15 degrees per hour which equals 1039mph @ the "RIM" of the disk, while holding the ring stationary. Now start migrating to the edge, when you get to the edge with your angular velocity in your head step off the angular velocity of 15 degrees per hour disc onto the stationary ring. LOL@UrSass!!!!!!! You will never make to the edge as the centrifugal force at just 300 miles out will throw you off the 3963 mile disk only rotating15 degrees per hour. It is called rim velocity for a reason.
Am I the only one who thinks the use of the vacuum and pressure gauge fittings for electrical continuity through the chamber walls is the most ingenious part of this setup? 😉
exactly same thought 👍👍
When i saw that i was like "thats big brain play right there."
I love this guy, he sounds so excited like its the first time he's ever seen his experiment.
He does the coolest experiments too, not lame stuff like you might see in your high school science class
Yah he's a great teacher 👍
@@hexedhydra2554 And he is also brainwashing you with the propaganda he is ordered to produce, too bad you are a gullible sheep and can not tell the difference between truth and fantasy.
@@idontcare7961 not sure whether I should ask if you’re okay or report for spam. What the shit are you talking about? You told me nothing about what I was supposedly blindly believing.
@@hexedhydra2554 Yes you just confirmed you are brainwashed.
Anyone see the fan ring grow in size during the spool-up? Too cool!
What I'm seeing the most is the ring/tip lifting while the center of the blade is struggling to detach from electric motor also the outer or the tip of the blade is traveling faster than the center and putting the two together this can snap the blade but maybe it was the centrifugal force or both lol
@@S3.14codm I think so too. The forces on the blade varies within the structure of the blade which creates warping and wobbling until the material strength snaps.
The engineers at nasa had to problem solve the exact same thing I think. And I wonder if they talk to engineers who design submarine propellers since they work under different pressure too. Much more pressure of course but there had to be similar problem solving
@@Heyitscryz submarines also have to try an compensate and minimise cavitation, as that is a massive problem giving the subs position away to passive sonar. They also tend to be Phosphor Bronze to reduce corrosion weight is not really a factor.

*Marshmallows slowly inflate*
“The reason violent things like this happen...”
If you were exposed to vacuum a similar thing would happen with your body, along with fluids boiling off.
Exactly XD
Yeah, that wouldn't feel nice inside your body
The point is marshmallows slowly inflating isn’t violent.
@@FrankyPi Not really. Only exposed fluids on your skin or tongue would vaporize, and you wouldn't bloat nearly as much as the marshmallows. What kills you in a vacuum is suffocation.

Ive been wondering this! Thankyou so much!

He is an example of perseverance.
Way to show your spirit.
Thanks for the Google easter egg about ingenuity!
After being introduced to your earlier episodes not long ago and having watches some of them, I can definetly say that you are becoming quite the science youtuber.
🖖
BTW, I today I got stuck in the CZcams shorts vacuum for about 3 hours, but along the way your videos made it slightly more bearable. Keep up the good content.
Awesome experiments😍
I wonder if nasa has a room-sized vacuum chamber to test these things.
Surely
Actually after I typed this I searched and found it. They do have one.
@@Yusso I Was going to tell you but as you hav already watched the test videos they did.
I learnt a lot from these home made experiments. Thank you very much
Great video!! You can also see the gyroscopic effect of the spinning blade, as it tries to remain it one orientation.
The second fan was scared to break apart like the first one, so jumped to disconnect the power supply; that is what happened.

What are you expecting to prove that you can’t calculate in advance?
I hope you get good results in your experiment with your car. 😀👍
Thanks guys! @Fred, to create an unlimited source of power! Naturally and nearly anywhere!
@@YoungMoneyFuture how is it unlimited? The amount of solar radiation converted to power is limited by the area of the panel.

@The Action Lab I am doing a distillation experiment and I am trying to find two liquids that are non-toxic/poisonous, not explosive, and overall safe to boil. Any recommendations?

Azidoazide azide but in liquid form... don't know how to make it liquid but I'm sure you'll figure it out... nahh forget making it liquid just shove it in a pan and try boiling it
Water and alcohol
coke would be good one, nothing like 40g of black goo to make a point
maybe water and glycerin

to mimic the approach used to make this work for ingenuity, you would need a propellor with signifcantly higher blade pitch. This means that the prop would be directing a larger volume of air downwards at the same RPM as a one of lower pitch. You can see in the photo of ingenuity that the blades have a massively steep pitch close to the hub, which tapers out towards the leading edge. This design ensures that an even amount of thrust is produced all the way along the blade, where a consistent pitch would see the bulk of the lift being generated near the tips, placing enormous stresses on the hub due to leverage. It also helps the prop cope with high rotational speeds, as the centre of mass of each blade sits closer to the hub, but you are still getting the advantage of a larger total surface area compared to a smaller diameter consistent-pitch prop with similar CoG characteristics. I would highly recommend trying this experiment again, but with a 5" FPV quadcopter triblade such as the Gemfan Hurricane 51499 or the T-Motor 5150 props. These are rated for extreme RPMs (40,000+ is typical for high performance racing drones) and they have an aggressive pitch that tapers along the blade. You may need to 3d a similar "floating mount" like you have here to take advantage of the 5mm shaft of a brushless racing drone motor, such as a 2207, high Kv brushless motor to achieve the desired RPMs. NASA really have those big blades spinning very fast for their size to make it fly, I think you would get impressive results with a similar approach
I have learned alot from you , and am inspired by you
Great experiment. It also proves something interesting, the reaction principle of propellers. I.E. That propellers do not act like screws that drive through air like in a solid but by accelerating gas particles backwards and this is why it works even at such low pressures.
@LabRat Knatz Ion wind is almost the same as ion thrusters that are used in spacecraft regularly now.
Do you think wings work by accelerating gas particles downwards?
@@ferrumignis No, they just create a pressure difference between the upper side and the lower one and this is why life is lost very quickly with altitude because the less initial pressure to work with, the less of a difference you can create.
@@ferrumignis However it is also because if this that flying with wings is much much more economical that flying on a vertical jet like a Harrier or F35 or the Lunar Module for that purpose. Flying with wings is just about geometry, like water skiing is not actually floating but just a dynamic phenomenon.
@@thelovertunisia _"No, they just create a pressure difference between the upper side and the lower one "_ Correct. A propeller is simply a moving wing, and operates on the same principal.
There was no offset for difference in gravity. New experiment with a machine that launches those rotors on mars.
Even better, It was able to fly in higher than Mars gravity with the same low atmosphere.
@Cheezl420 Says fuq it Then what do you call the force that makes a moon orbit a planet or planets around a star or even holds you down to the ground?
@Cheezl420 Says fuq it Yep there is it...Flatard comment. I gave you a chance to not be one, but you sure did.

Loved the video!
Amazing content always!
I waited this video.. finally.
The earth's atmosphere has that pressure at 31,000 m.
Helicopters can't fly over everest or to the camping the death zone and everest is only 29000ft
@@mickjenner6697 Of course normal helicopters can't fly on Mars or at 31,000 m.
@@1.4142 I don't think rockets can work in the vacuum of space either ,, and as there is no way to stabalize flight in space with wings or airlorans im pretty sure all nasa claimsare bunk
@@mickjenner6697 Rockets don't need air to function or stabilize. They can change the direction of thrusters and use Spin-stabilisation.
The blade-only work around is pretty brilliant, I have to say. I was asking myself this question as soon as I saw the thumbnail/title. Ingenuity, indeed. LoL
That was very interesting thanks for sharing
5:30. That actually really only looks like Gyroscopic, Centripetal and Centrifugal forces at play. Due to the vacuum.
Congratulations you've just discovered anti-gravity.! And all by yourself.!
Try doing the same thing but removing the angle on the blades or replace the blades all together with little aerodynamic Support Beams.
So that you can rule out aerodynamic lift all together.
The ONLY thing we need to find out:
can a FLY fly in martian atmosphere?
It has been done, and the answer is not.
But different species of flies should be tested, there must be some with high twr.
When I was a kid in 1972, we had toy flying props like that. Some launchers had a 'C' cell and motor with a gun-like trigger. Others had a string to pull or a coil spring to wind up.
Those actually came back around several times in the 80s and 90s, too.
I love your method for getting electricity inside the chamber!
I clicked faster than *Ý Ə §*
4:24 Just as the rotor was leaving, it swung slightly and therefore grabbed the white power cord and broke. If you are a real scientist, you need to take things into account and prepare for the experiment much better. But if you're just a clown, then all is well.

Congrats bri
I love how you used the pump and pressure gauge as part of your wiring.
What would happen if you put a Li-ion battery in the vacuum?
Well.. I didn't see that coming. Awesome demonstration.
Sir i think you are the son of science I can't explain how good your explanation is
I really think focus us in create ways for generate specifics artificial atmospheres in order to change eventually the conditions and parameters in one planet is the first step for prepare a place for go there in future... great interesting video and experiment ... loving the content here ...
If I was there I would have broken all three. The sense of responsibility of this guy!
To find more exactly the lowest pressure your thingy can fly in; mount the rig upside-down on the lid and run the motor in reverse, then slowly suck the air out of the chamber. The thingy will drop when it can't push against the motor anymore.
I would like to see what the results of mixing Novec 649 mixed with your dry water emulsion would be. 💯💯💯 I love your content and will continue to be inspired by your experiments.
You can see the circle holding the blades together flex out like crazy
I love the wiring lol, funny and clever at the same time
really nice explanation. 👍
My heart was bumping damn fast🔥
I love this man ❤️
in the near vacuum, the downward pressure from the spinning blades would likely be minimal in ratio to the amount of vacuum (lack of air to enable lift) in the chamber.
2:13, snap circuits motor!
Awesome content 🎉
Very well explained
Since ending up with three different results I suggest you try this experiment again, but put sand or feathers on the bottom of the chamber.
The effects of Mars’ atmosphere are covered in depth in a documentary called Total Recall
*Very* accessible experiment. Now I want to build a vacuum chamber!
That motor brings back memories of my childhood...
Put the scale under a transparent cover which is larger than the scale and rests on the floor of the vacuum chamber, with a small hole on top for the propeller shaft to go to the prop. In this way, the motor will be on the scale under the cover, which will permit observation of the weight on the scale. The lift generated by the propeller will not be offset by the downdraft, and thus an estimate of the lift force can be measured.
If you suspended a baffle above the motor and below the propeller you could get a better reading of total lift. Much like running your motor through your scale as far as results go .
Maybe put a shield "table" over the scale with a small hole for a ~2 cm block to go through, on which you can rest the apparatus, to shield the scales from downward air?
You got the attention of this quadcopter pilot. ✌😉
Very informative for space lovers
What about the idea of supporting the motor and blades etc on a “see-saw” that mimics the gravity of Mars by having a counterweight.
Amazing mate!
You could 3D print a windshield for the scale, which stands on the ground. So the downwind won't hit the scale.
That's funny I was dreaming up an experiment like this when I was thinking about how thin the atmosphere on Mars is .
Nice use of snap circuits
I guess you could make a shield for the scale, so that just the output shaft from the motor stuck out, and the outside could rest on the body of the scale.
Might try and see if light diminishes in a vacuum as the pressure drives down ,so less molecules floating around . I was amazed that Mars could have a bright sunny day with such a thin atmosphere .
I think you have done a very good experiment that drone cannot fly in extremely low atmospheric pressure
I love how it tried to take the motor with it first
Great experiment
We know that spinning the plastic fan will stretch it(as shown by it exploding), I feel that the center of it will also stretch/expand, but likely unevenly because of the attachment points of the blade. This could easily grip down on the electric motor adapter causing it to need more energy to actually "release" the fan blade.
