That ending caught me off guard. I'm too used to the cool thing followed by explanation formula.

It has a really simple explanation

According to the Action Lab there's 3 things that allow the gauge blocks to wring together. 1. Surface tension of the oil. 2. A vacuum/ low air pressure in between the blocks. 3. Electrical bonding of the atoms.

Did he credit Codyslab? He doesn't usually credit where he took the idea/information from. Usually just regurgitating other peoples work in a slightly less accurate form and often an incompetent, incoherent, or incomplete, experimental method. Basically science click bait that almost pays off.

How good is Action Lab today? In the past he would glue them together and apologised for the clickbait…

Action Lab just parrots popsci blogposts without understanding anything, sometimes even getting things wrong entirely. Don't trust Action Lab.

The vacuum/ pressure theory has now been dismissed as the blocks will still wring together in a vacuum. I’m sure there will be a tiny force when in atmospheric pressure but it doesn’t explain the wringing.

@granthollingsworth230 Жыл бұрын

A large amount of atoms from each block are so microscopically close to one another, thanks to precision flatness and polishing, the charge of the atoms from each block actually attract each other.

It’s called mechanical bonding, you have created a vacuum between the blocks and that causes them the stick together. I’m a heat treater, I’ve done a lot of stupid things. Once I made some spacer blocks from 316 steel to support a large CA6NM casting during a vacuum normalizing process, the casting had a machined surface and the spacer blocks were smooth. Both metals expanded while they were hot, I had removed the atmosphere in the vacuum chamber and so they got stuck together. We had to remove the spacer from the machined surface with a sledge hammer. Unfortunately I am a klutz, and so there’s a nuclear reactor somewhere in the world with a housing with a big dent in it. You’re welcome world. Now I know to use ceramic plates

Is this to do with Van Der Waals forces? I feel like they're soo smooth that they almost have their molecules coming into contact - sort of like a nano-tape type thing since you slid it on an pushed the air out?

@innersourcemediagroupllc820 5 ай бұрын

Surface tension from oil and water vapor that is present between the blocks. Molecular attraction that occurs when two very flat surfaces are brought into contact; this force causes gauge blocks to adhere even without surface lubricants, and in a vacuum.

You could check it for vacuum. It looks like those are stuck together with a force that's greater than 14.7 psi, so I'm guessing they're cold-welding together.

Look up Codyslab experiments on this if you're interested. He tests a lot of theories on how this works and makes some interesting discoveries.

@lumarans30 5 ай бұрын

I think this is due to Van der Waals forces, the same ones that enable geckos to climb smooth surfaces like glass. I wonder, though, how does it differ from the Casimir effect?

Just before the end of the video, I was going to google this to see why it happens. Damn

@Leo99929 2 жыл бұрын

Codyslab has done some interesting experiments on this. A non zero amount of liquid on the surface was required to make it work, if I remember correctly. Works with ceramic and metal gauge blocks. They don't unstick if put in a vacuum. They don't stick if put together in a vacuum and then atmosphere applied. It could be a lot of things like maybe van der Waals forces or surface tension, but at least not primarily a vacuum.

Statistical quantum mechanics states that the electron density of an atom is subject to purturbations which result in the formation of temporary dipoles. Or rather, electrical charge sloshes about which forms mini magnets that attract. Lots of them close together is noticeable.

If they are the same material couldn't the friction from the rubbing together remove any oxide layers from the surface and allow the two pieces to self weld?

I was told it was due to vaccum(suction)

@Leo99929 2 жыл бұрын

Codyslab tested this and the results didn't support this narrative. I think he did however find that a non zero amount of oil or liquid was required on the surface in order for them to stick together.

@dhavalghone9398 2 жыл бұрын

I think this is because they are so smooth, they trap no air between them so they are held by vaccum. I observed a similar phenomenon with carrom strikers when they are stuck bottom to bottom, they will stay stick as well

The effect also works in a vacuum tho

I think it is caused by Van Der Waal forces (the forces that allow geckos to climb on smooth surfaces like glass).
