In this video I see what happens when you fill an air mattress with helium! Can you actually ride it like a magic carpet? Does it float. Then I try filling a bike tire with helium to see if it makes the bike tire any lighter. Then I talk about helium and why we are running out of helium. How is it produced and where is it going? Will we run out of helium on earth?

A pure hydrogen balloon won't explode if you light it on fire.
It'll burn as a rising fireball as the hydrogen escapes and you might ignite the latex
Now if I was sleeping in a small room with that mattress and it deflated, I'd be breathing in some really funny air.

We could also build vacuum balloons. If you find a material that is super lightweight and strong enough to withstand atmospheric pressure, you could make a balloon out of it, suck out (almost) all the air from inside and it will raise because it also displaces air and unlike helium or hydrogen, it has no density whatsoever, so it will raise even stronger.
You can float a medium size metal sphere with a thin wall (and filled with plain air) in Xenon gas. Rule of thumb (Archimedes law): the buoyancy force is equal the weight of the displaced medium (in your case air, in my case Xenon)

We used to use helium in air suspension for hopping. As he said the speed of helium. It charges to the air spring faster than air giving more energy at inflation.
Another thing we noticed was the molecules were smaller and able the permeate the air spring. So if you had one full of C02, 02, and helium, the helium one would deflate as the molecules passed through the rubber.
it's even worse for hydrogen - it slowly escapes from aluminium tanks through the crystal itself

The question I wonder about though: is it more comfortable with helium? I know it is a subjective thing, I knew it wouldn't float, but what does it feel like?

This is why we have a helium shortage
It made me cringe seeing all of that helium wasted!
He should have used hydrogen instead of wasting such a precious gas. That actually gives slightly more lift than helium and is not that dangerous if you make shure to have no flames or hot objects nearby (also - since it's contained in the mattress, it will not ignite just because of a small spark or static electricity)
I know this is a joke or at least I think it is, but the sun has a shit ton of helium, more than we could ever use.
@@greyhead3626 and how do you propose we get it?
@@greyhead3626 Yes, it should be a simple matter of sending a few tankers to the sun to collect it and bring it back. No problem.

Thanks heaps for the great explanation. So would the helium when it's first released from the balloon and is still together, initially start to rise up and stop after it spreads too far? Or does it just disperse as soon as it hits the air? Then would the helium particles just randomly move around in the air? Is there any attraction for the helium atoms to be drawn to each other like we see with liquids? Or for example how smoke accumulates at the top of a room. I'm assuming the density is sufficient for it to displace the air however doesn't that still require the smoke atoms to stay together. For example would one of those smoke atoms if taken and placed in air float to the top? If not what keeps the smoke atoms together so that it can displace enough air to float. Wouldn't they just disperse into the air as well?
i found this really interesting so i wanna try and answer. i think a good way to think about helium in air is to compare it to something like pouring really salty/sugary water into plain water, but upside down. the denser liquid stays together and sinks for a little bit, but in a tall enough glass would eventually spread out and mix with the plain water until the densities were the same. similarly the helium would rise for a bit before spreading out. also, there isn’t any attraction between helium atoms, they are completely non-polar. the molecules sticking together is actually what determines if a substance is solid/liquid/gas at a certain temp, so water needs to be pretty sticky to not just turn into vapour. helium is so not attracted to itself that you need to get it extremely cold temps before it can stay as a liquid. for the smoke, i looked into it a bit and i think it’s because smoke only rises when it’s hot, and it can only cool down by bumping into cooler molecules. that means that when the smoke is all together, it doesn’t lose much heat and once it hits the ceiling there isn’t anywhere to spread out so it stays as a pocket of warm air. smoke that’s cool would i think be denser than air, especially the particles that you can see which i believe are just tiny bits of carbon. hope this makes sense :)
What he said about the helium stopping after a while is bullshit. It's lighter than air, than any atmosphere- it keeps rising and leaves the atmosphere and into space where it disperses as any gas does in space. It's the only element that passes through the atmosphere and escapes into space naturally. No helium resides in the atmosphere- it's all just passing through. And as for salty water and fresh, there are undersea places where layers of brine do not mix with normal seawater, and places where fresh and salt stay seperate in layers.
In order to float, the total density would need to be less than that of air. The density of air is approximately 1.225 kg/m³. If the weight of the man, clothing, mattress, and the gas is, 100kg, you would need the composite volume of 81.633 m³ to float. If your bedroom is 4m x 4m x 4m, your bedroom is smaller than this.

The US government has been hoarding helium since the 1870s. The Hindenburg disaster was caused by the US not selling Germany helium, and it wasn't be cause if Hitler, we wouldn't have even considered parting with that much to anyone for any price at that time. The US has also been fracking for natural gas so should have too much, but oddly, we have too little.
Where is it? Its with the strategic oil reserves, down in old oil wells that have "dried up." I wanna know what they are going to do with it, probably something really cool.

@@AnonEyeMouse it’s a joke -_-
Hindenburg caught alight due to the paint used on the canvas when it made contact with its holding stand, it caused a spark that ignited its paint thus the way it started from the top of the ship and went across it in seconds whereas if the hydrogen was at fault it would’ve caused an explosion then self extinguish as the gas would’ve burned off.
This is why airships of today (50 years) are made of a rubber compound developed by Goodyear.
You should try to do this again, but with one of the thicker air mattresses so that it can hold more helium or use multiple air mattresses

Something else that reduces the lifting power is the pressure that the object is inflated to, as it compresses the helium making it more dense. This method of varying lift has been used by Goodyear for a long time, there is a ballonet inside the main bag along with the helium. To reduce the lift more air is pumped into the ballonet which compresses the helium bag and allows the airship to descend. The pressure is released to climb. And no helium is released so the only wastage is due to seepage.

I read somewhere that helium comes out of the ground (?) and actually leaves the astrosphere. Huge bags of helium used to lift heavy items out of our astrosphere??
as for bike tires the benefit there is if a tire calls for say 95-100 psi with air. you can go 190-200 helium which makes the tire harder and less friction when pushing it. makes for an interesting blowout if you should have one .
95 psi is 95 psi- doesn't matter which gas it is, the tyre still bursts if you go over max recommended pressure.

When it started floating, i admit you had me.
2:45 really got me there
The difference in the up and down force is 0.069 pounds. Therefore each cubic foot of helium could lift 0.069 pounds. In order to lift 100 pounds (which would include the weight of your load, the balloon, and the helium) you would need 1449 cubic feet of helium.
Your mattress holds maybe 30 cubic feet, and you weight more than 100lbs, so you would need about 100 mattresses to float 200lbs.
equations or doesn’t count. 😹👏
Weight of air: 1.225 kg/m^3
Weight of helium: 0.1785 kg/m^3 kilogram per cubic meter
So, for every cubic meter of air, displaced by helium, you get a lift of 1.225 - 0.1785 = 1.0465 kg (roughly 1kg).
The air mattress weighed 3.753 kg 1:18
Dimensions of a queen mattress are 152.4cm x 213.36cm x Depth (lets assume a depth of 30.5cm) = volume 1m^3 (super convenient!)
So total lift is 1 kg total weight of mattress is 3.753kg .... totally predictable total failure is totally achieved

A cubic metre of air weighs around 1kg. Even if the air mattress had weighed just 1kg, it would need to have a volume of 1 cubic metre to have neutral buoyancy even with a vacuum inside. Add the weight of the helium (about 0.17kg at standard atmospheric pressure and temperature) and you'd need around 1.2 cubic metres. This mattress weighed over three times that and a tape measure would tell you it's barely a cubic metre in volume.
Use a light weight matress made of balloon type rubber material..than only it will float ( without heavy object ) ☑️

I'm at the start at the video but I think there is absolutely no way you could float on that. I'm not even sure the mattress will entirely lift.
when fusion reactors are perfected and used around the world they'll convert a lot of hydrogen into helium and thus we won't have a helium shortage.

Fun fact: NASCAR pit teams found that the tool (forget it's name) that puts in the bolts that hold wheels in the car are about a tenth of a second faster when using compressed helium instead of compressed air

@Luxury Inc as a refrigerant, for example in superconducting magnets for MRI scanners. It’s literally saving people’s lives.
Superconductors that would already work with liquid nitrogen like YBCO would be way too expensive/fragile to build a huge electromagnet out of them. There are cheaper and easier to work with superconductors like Niobium, but that requires liquid helium cooling.

I believe the mattress would have been even lighter if you had measured it flat. The helium needs more surface area to push up against. Holding the mattress up and down decreases surface area to push up against.
Nonsense!
So you think if I get on the bathroom scales horizontally, they'll read heavier? Must be why ships are too heavy to fly without wings but rockets can get into space......
@Ross Brumby no but you will displace less pounds per square inch. Just like a helium tank will not float away unless you fill a large balloon with the helium in the tank to lift it.
would a helium bubble raise faster than an air bubble underwater eg take a bottle filled with each scuba diving and open them down a few hundred feet and open them?
